Going outside of manufacturers suggestions

[dieseluser07]

My warranty is essentially void as my car is remapped, aftermarket intercooler fitted etc.

So ive decided to get my car serviced by a well known reputable tuning company who use oil that no other garage uses.

The car is reccomended 5w20 or 5w30. They use millers nanodrive 5w40. Basically saying on tuned engines it provides better protection etc. They havent had any issues using it apparently on their in house work cars that are highly tuned.

Is there any chance this could cause lasting harm to the engine due to it being more viscous? Seeing as ive voided my warranty im trying to stay on the safe side.

Well if it was me I'd stick to using oil that the manufacturer recommends for your engine.

Nanodrive oil is great.... ive used it for the last 4-5years

Sounds like you have a TFSi of some sort..
I used 5W40 in my Audi S3, 5W30 would last a week...
Went to have it serviced in Audi and had to sign a disclamer that they were putting customer supplied oil in and it was the incorrect grade.

The hot grade is the one that matters most. The proposed oil is a bit thicker when hot, which is likely to give it a higher film strength, but even so it will be massively thinner than any grade when cold. You already know that the engine survives cold starts without any nasty oil pressure related damage so there's no reason to expect damage from running this slightly thicker oil when hot.

ETA:
If you have any sort of warranty covering the engine and want to preserve that, then the warranty terms would trump any practical considerations. But from what you wrote previously, I don't think that's the case.

I do, well i did have a warranty but the car has a stage 2 remap on it and from what i have been told they would be able to see the ecu has been tampered with, even if i put the standard map back on so i think im pretty screwed lol.

Interesting, reason I said as using Millers 5w40 on the 2.0 TFSi has become standard for many tuned VAG engines due to oil issues.

Tbh this engine itself is known to be strong and handle 350bhp on standard internals. (There was a coolant recall because the pipes were bursting and melting cylinder heads but thats all been recalled to the cars effected), when i was asked it was purely because they dont think the standard 5w20/5w30 protects the engine well enough on a tuned engine so i dont know tbh. The oil has got an excellent write up though.

Did you run different oil in the other exact same car which is subject to the same usage conditions and how did you verify which one was best?

[AJB88]

Always used Nanodrive on my VW group cars Stage2 + and been fine.

5w40? When your car was reccomended with less??

Yes. Less wear on fuel pump cam follower for one....

Yep I ran Millers Nanodrive CFS 5W-40 NT+ "motorsport engine oil"

Thats the one.

My car is 5w20 and 5w30 is also an option but 5w40 isent a reccomended oil for my engine, yet this local tuner seem confident in it.

Really? You conducted a back to back test of two identical engines, run in identical conditions, with one on a control oil (so for un-named) and one on Nanodrive? Just so you could find which oil was better?

And your discovery was that the fuel pump cam had less wear. Just that? Nothing else on bearings, rings, bores, cam followers etc?

I don't mean to pick on anyone, but here's the thing with oils, they are surrounded my marketing bullst. Bullst which is impossible to disprove for the average user. There is no independent empirical testing of engine oils.

Within the regulations of what can and cannot be added to oils, there are strict limits due to toxicity and environmental impact therefore there is little scope for a breakthrough invention.

Any ester based synthetic of the correct grade will be sufficient. If an engine is experiencing excessively high oil temperatures, increase oil cooling. If not possible, you could go up a grade, but above 125degC, the oil degrades much faster, so increased intervals are also advisory. At the price of these types of oils, it is cheaper in the long run to improve cooling.

Don’t be a clown....

From my observations of running my car on OEM oil vs millers, less wear on said component.

Hartech Porsche engine rebuilders recommend millers oil too.... I would imagine they know what they are doing.

But here's the thing, Millers have had a breakthrough with their use of nano bucky balls to reduce friction. They've even won several prestigious motorsport technology awards for it against the likes of McLaren, Zytek, Gill Sensors; not something you'd manage if it were just marketing spiel.

If we are to believe the claims made by Miller

Fully synthetic Triple Ester Nano Technology Oil provides:
• Laboratory tests and results show up to a further 15% reduction in friction and up to a further 17% reduction in wear over the previous award winning NT range
• Significantly reduced friction
• Reduced component wear promotes longer engine life
• Reduced heat production
• Increased power output and torque
• Improved reliability
• Improved energy efficiency
• Superior anti-friction and anti-wear characteristics

Why haven't all the OEM cottoned on and specified it a OEM oil if it so much better? How much do you think OEMs are spending on R&D to reduce friction?

Maybe it cost too much for manufacturers to use it and isent worth it unless its a highly stressed engine
