Engine Oil Deals & Offers

Snake oil.. . ...I got in first this time....

£2 for the petrol one on Amazon too. I bought it because it should work out cheaper wth regular supermarket fuel rather than the BP Ultimate that I use occassionally.... and because I needed to spend another couple of quid to get free delivery.

Waste of time and money, a placebo product

The question people need to ask themselves is how realistic is it that a bottle of this stuff mixed in with 40+ litres of fuel then sprayed through a high pressure nozzle (effectively) once in a while is going to make a difference? Compare that with what it's like to use fairy liquid and a scourer, trying to clean up a used grill with elbow grease, it takes a huge effort for little gain. Silly comparison, but in some ways not. Just puts a bit of perspective on it. Failing that, then take far the simpler business view. If it worked there would be marketing photos and videos all over YouTube and the internet. Not the ridiculous fifth gear video which has far too many variables to be taken seriously. You could take 3, 5 or even 10 high mileage cars. Run 5 with and 5 without for 5 tanks of fuel. Pull out the injectors, use a endescope and do before and after photos and videos. It'd be so easy to prove this stuff works and not expensive, yet I've never seen Redex or anyone else do it. Now I wonder why that might be....

Excellent information, esp the tip to stick the injectors in an ultrasonic cleaner, thanks.

Yep, better to put three litres of fuel in your car and take it for a spirited drive along a road where you can keep your speed up.

If you look at the Redex data sheets from the manufacturer you'll see that all varieties, whether petrol or diesel, have 60-100% Naptha in them. It'll make bugger all difference to anything whichever you put in.

No thats the wrong item you are looking at, thats diesel cleaner, DPF cleaner is £6 in Asda (y)

Only £2 in Asda

I just go for a 20 minute drive down a duel carriage way and that clears the dpf, tried this stuff once and I wasn't impressed

This seller has some really good prices; just ordered a couple of tubs of brake fluid for not much at all. It's a perfectly decent brand of oil, and plenty of garages use it for the common flavours (5w/30 etc).

Remind me not to buy that from you when you sell it (:I (y)

Some of the newer VW group cars (eg Mk 7 golf R) are designed to suck the oil out as the sump and bung are made of plastic and isn't a proper bung it's a little half turn type thing. Not my cup of tea

Most garages suck it out now and dont even remove the sump plug leaving some of the crud in the bottom so I prefer to do it myself

Dead simple. Would recommend a set of axle stands or ramps as you have to get the sump plug off from under the car. I've got a thing like this for catching the used oil and taking it to the tip https://www.demon-tweeks.com/demon-tweeks-oil-drain-pan-storage-container-jerjc008dr/?istCompanyId=a2904180-3a7d-4e56-b876-cf81c9512180&istFeedId=6fbc4b04-fd28-4ce1-8513-835c8f118690&istItemId=wptpparaw&istBid=t&gclsrc=aw.ds&&gclid=Cj0KCQjwka_1BRCPARIsAMlUmEr9WpK4dM30_soLQJZmZpxAHZ7jKV_CbtlGQXqDfkGsSjInDoiWdXAaArqIEALw_wcB

I’ve not owned a car in 15 years that doesn’t need more than 4 litres. Most other lube manufacturers sell their products in 5litre containers. Wish Castrol would do the same.

Whatever you do, DONT order parts from these: https://www.autodoc.co.uk/ https://www.buycarparts.co.uk/ https://www.onlinecarparts.co.uk/ I have just been waiting over 3 weeks for parts to arrive without any notification from them to say they had been dispatched or anything. All 3 sites are run by the same company, and they are based in GERMANY - NOT THE UK. Its deliberately misleading since their sites are a .co.uk address. The parts are shipped from Germany and it means you are waiting ages for them to arrive. Carparts4less/eurocarparts have always delivered within 2 days of ordering to me, and at least tits a British company. There is always GSF as an option either.

Maybe filters out of stock :D

Terrible company still waiting for my order from March no response from emails at all absolutely terrible company I will never order from this company again

Carparts4less are getting absolutely slated on trust pilot at the minute for none delivery and ignoring communication. I have an outstanding order with them for £100 worth of stuff, 9 days so far and nothig yet. Buyer beware.

You were lucky ;) I'm pleased it worked for you, The other stuff I recommended will work even better since it's better stuff ;) Some folk even add a bit of 2 stroke oil to it to aid lubrication.

Well it worked in mine (y)

Redex is a poor performing additive, Besides it's pretty easy for a diesel to pass emissions if the DPF if is working as it should be. It's most probably just luck. It contains an ingredient called 2-EHN 2-Ethyl Hexyl Nitrate and there is some science behind it but it contains it in very small quantities. If you want to use additives that will actually work much better for diesels then I'd recommend this stuff it's 99% rather than 5%. It can potentially lower the combustion temp of the diesel, Hence it burns more efficiently and helps with DPF regeneration active and passive etc.. It won't clean as such but can help clear the DPF. To clean I'd recommend Seafoam it's the only additive that I've seen genuinely clean carbon off pistons etc.. Yes on older cars Redex has been known to help restore a little power but it won't do much to a modern car. There are loads of additives out there that do a much better job but in general they're a waste of money. Your car really shouldn't need them, It won't be long before the engine lights back on ;) Also changing the oil frequently will help more, During active regeneration's the diesel can end up mixing with the oil, This can increase the oil level and dilute it so it doesn't lubricate as well and can eat away at various different seals causing leaks and in some cases engines blowing up due to the increasing pressure due to oil level! Especially if active regeneration's are cut short and you do lots of short journeys etc.. Short journeys equal more carbon buildup, more carbon build up equals more active regeneration's more regeneration's equal more diesel in the oil etc.. I'd recommend changing it every 6k or maybe even less if lots of stop start, short journeys etc.. Doesn't matter what oil so long as it meets manufacturers minimum specs. Me personally, I've tried 2-EHN 2-Ethyl Hexyl Nitrate and didn't notice any difference but mines a relatively modern car.

Snake oil

I had a 2006 ford focus diesel. failed emissions. I tried everything to get it to pass including driving about 50 miles at high speed in low gear for Italian tune up. Still failed. Told by a mechanic friend to give one last shot using this. Car passed with flying colours and still on road (y)

Had DPF light on and this worked for me, cannot complain.

Put some in my transit custom a while back just as a precaution a few days later I got the warning notification telling me to drive the van to clean the dpf I'll never waste my money on this stuff again

Look up the manufacturer's ingredients sheets for redex. Whichever one you look at petrol/diesel/dpf cleaner/pre Mot they are all listed at 60-100% naptha.

Quite often Tesco/Asda put these on sale 2 pounds each, cold for me

DPF Cleaner lowers the temperature the soot burns at, meaning it burns away during normal driving without you having to get your engine very hot. Works for me, and has done for over seven years in my diesel powered car with a DPF. Never once had any DPF issues.

For every 10 morons that buy into any bit of marketing they think they understand, and don’t actually read what is written, there will be 1 or 2 experienced mechanical engineers that understand what you are spouting is absolute nonsense.

For every one person who doesn't understand or listen, there will be 10 who will take it on board and think twice before potentially invalidating their warranty, go against their car manufacturer and shorten the life of their complicated engines and expensive catalytic converters etc. Have a nice day.

None of which say they'll definitely void your warranty. Look at the language used. They just want you to purchase the genuine equivalents. Well done for trying to win an argument via Googling things quickly.

A very quick google of a Volvo manual - https://www.volvocars.com/en-th/support/manuals/xc40/2019-early/starting-and-driving/fuel/petrol IMPORTANT Do not use any additives which have not been recommended by Volvo. A quick google and information from Ford - Fuel Additives It should not be necessary to add any aftermarket additives to your fuel if you use a high quality diesel fuel that conforms to ASTM industry specifications. Aftermarket additives can damage the fuel injector system or engine. From a Ford Mustang Manual "Do not add aftermarket fuel additive products to your fuel tank. It should not be necessary to add any aftermarket products to your fuel tank if you continue to use high quality fuel of the recommended octane rating. These products have not been approved for your engine and could cause damage to the fuel system. Repairs to correct the effects of using an aftermarket product in your fuel may not be covered by your warranty." NISSAN Aftermarket fuel additives: NISSAN does not recommend the use of any fuel additives (that is, fuel injector cleaner, octane booster, intake valve deposit removers, etc.) which are sold commercially. Many of these additives intended for gum, varnish or deposit removal may contain active solvent or similar ingredients that can be harmful to the fuel system and engine.

Absolute tosh; dangerous misinformation. I've worked in the aftermarket for years and OEM-side as well, and can categorically assure you that this is not true. Where have you read this / who has told you? Redex wouldn't be my choice personally, but this is a good price. If you want a premium product, Archoil is pretty good but expensive.

Yeah, it's good that the UK seems pretty strict. Which is odd how stuff like redex gets sold and it pretty dubious. I think it's more about preventing harm. I.e. bad oil will kill your car so needs looking at, Redex doesn't do any harm, (or any good probably) so it's ignored.

Thanks, interesting link, I've often wondered if anyone ever checks that oils actually meet the spec that they claim to... after all, anyone can get a label printed!

Heat this is freaking great deal. If only I have the space and tools to do the oil change myself I will snap this up. Need my own driveway first then some axle stands, jacks I already have. As long as it meets spec then these are absolutely fine. Change once a year. No need to spend a ton on Mobil oil.

Also, have a look here: http://ukla-vls.org.uk/ Independent tests on oils o check they are up to spec. As in proper tests, not just autoexpress or 5th gear doing a pointless back to back dyno run.

oil specs are a bit complex but can be found on the web: https://www.opieoils.co.uk/t-acea-car-engine-oils-specification-explained.aspx Just a thought, these companies dont have an old man brewing the stuff up in their back kitchen, they buy in from the oil suppliers, and re badge, sometimes a bit of research will tell you a lot, try looking at the specification sheets of Halfords own oil which they put on their web site.

Would this work on a car with a supercharger eg an old mercedes kompressor engine?

It's £2 in Tesco now too

Take it for an Italian tune-up

I just got the diesel one for £2 from Asda in my delivery. It was £4 a few days ago and more elsewhere. We don't have a Tesco nearby, it'd cost more to drive to pick it up than to get it through prime. I know some places have it at £2 more often, but the ease of prime is why I posted. :)

Awarded heat but Tesco's regularly have it and the diesel additive at this price, and claim it is reduced from £4 i.e. a half price offer. So whilst overstating the discount it's a good price.

Showing as £30.99 now? Still cheaper than most

Okay buddy... 🤪

I've found it plenty enough to do around 600 rashers of bacon.

2.0Tdi would be enough as when you drain oil you won't get all of it out.....so around 3.8 litres are required for for 2 litre tdi.....always get a 4 litre tub .....Petronas long life. 5w30 vw 507 but if your engine drinks then I recommend 5 litre for top up.

Oil specs are very confusing these days but many people (on HUKD at least) don't seem to even want to understand. Which would you trust more: information from the manufacturer or some possible numpty on HUKD? If you just buy oil based on viscosity, as long as it's close to what your car needs it's not going to cause any noticeable damage in the short term. However, if you have a decent, high value car then ensuring you stick strictly to the manufacturer's recommendation (full spec, not brand) is the cheapest way to ensure the long life of your engine. Changing the oil more often than required is still cheap preventative maintenance. Getting remarkably high outputs from small engines with long service intervals requires some exceptional engineering which needs protection and your DPF, cat, etc. are also at risk from incorrect oils. If you've got an old knacker with all the oily bits well worn that you're just running until the MoT expires then anything cheap, brown and runny will probably do the job for a while! XD

They provide you with the filter specific to your vehicle. However they don't stock the filter for a 1UZ-FE engine so I'm out of luck. Heat anyway.

The filter is very random isn't it....They are car specific.

Whats the star about next to deals?

Very good price, supposed to use 30 in mine but this’ll do

thanks for repeating what I'd already said...

I’ve seen it under £30. This ain’t a good deal.

I got 8 bottles from that deal so I’m sorted for 4 oil changes.

Mine didn't turn up

yeh it's very good and meets all the standards. You do have to wonder about all these "mega" oils claiming X,Y,Z, yet these "cheap" oils meet the manufacturers standards. They're not going to accredit crap...!

You'll be in the forefront of my mind... (annoyed)

Took them 3 days to send me that, no mention of actually sending me my correct oil, never again will i order off euro car parts, 25y iv supported them,

New message from: carpartssaver (629,342)Dear Customer, Thank you for your message. We will accept a return if the item is incorrect. If you wish to return this item, please provide a suitable collection date (Monday - Friday) and we can arrange a collection with DHL. I apologise for any inconvenience caused. Kind regards, Denis

Hopefully the next time you see it at £18 or less you'll take time out to upload it then squire. (y)

Just got this for 17ish last week I think

Great saving as its currently £26.35 on amazon and £20.95 +delivery on opie oils website so you saved me a few quid as was getting some this week anyway.

I've personally used Triple QX solely for God knows how many years in the same car and never had an issue with it.

Aye, but the topic is really about the oil. (y)

And nobody has ever come out to scupper it or say that the oil is indeed of poor quality. (y) That suggests to me that the oil is OK

There are a lot of idiots on that thread, "At present I change my oil between 1.5-2k"

So long as it meets your manufacturers minimum specs then it's perfectly good enough oil.
