Oil grades

[aalveris]

I use 5w40 full synthetic silkolene pro s and no use of oil,2+bar presure on hot idle and the car is 163k

I took the advice given on this forum a few years back and have used 10w 50 Fuchs Titan Pro S every 5k miles since (ADU)

Sometimes needs a top up between 4-4.5k miles but uses very little, engine now on 162k (miles).

Just had an oil and filter change and literally just back from a 420 mile round trip and it's running lovely, flew back up the motorways, hardly any traffic....rare these days!

Lots of views as always, I gotta say had 5-30 in for 6 months all pressures correct no noise no oil use seems to run fine on it but have changed to 5-40 now.

I am using Fuchs 10w50

Ditto, use the now badged titan pro-s race oil in 10w50 in my uprated 3B.. Great oil

[anthonys2]

I use either 5w30 or 5w40 either one works for me and mine hardly uses any oil between its yearly changes and rarely goes black/brown

I use 10w/50 Fuchs/Silkolene Pro S in my motor and I can't fault it. Tried the Millers 10w/50 CFS one oil change ago and the car started smoking on startup. Swapped back to Pro S again and absolutely no smoking. Strange as you would think the oil viscosity would potentially cause the issue and they should be the same...

Strange one that, not sure why or how the Millers oil would particularly cause that issue. The CFS and Pro S are both a PAO/Ester group V oil, and I've used CFS in my last two 5-pot turbo's with no problems whatsoever, quite the reverse actually.
