Goodevening gents,

I need your opinion on which engine oil I should use in my car.

I have some choices e.g.:

Mobil1 0w40 new life (SM/CF)

Shell helix racing 10w60 (SM/CF)

And motul 5w50 (SM/CF)

any other engine oils that I can use or are these the best engine oil I can use?

I use the Motul 5-50W which is superior to the Mobil 1 as far as I understand. Litchfield Imports offer the Motul option over the Mobil 1 if you want it whilst servicing. There may be better oils for racing etc. out there, but my understanding is that this is a very good oil indeed. Others will probably chime in.

I am testing shell helix racing 10w60 sm spec at the moment.

drives ok and feels more responsive than the OEM oil.

+1 on this, Motul 5W/50 Sport is the way to go IMHO!

how are you testing?
1. Jacking up all wheels and run it flat for a few hours.
2. Dyno it for a day long
3. 1/4 mile for 3 hours.
4. daily use tests.
5. idling test with degrading levels.

Don't worry I have plenty of 10w60 left about 15L.

testing temps with daily drive around 85C.

I guess what I meant to say was - how are you coming to conclusions from your tests?

As far as I have understood, a different oil does not let the car run cooler - but a 60W oil will stay a bot more viscous at higher temps than a 40W - if all things being equal - and so provides more consistent protection but doesn't affect temperature at all.

In any case, after the "tests" - how do you decide on the results? Are you sending the oils away for testing?

Maybe I have misunderstood something, but I cannot help think that this will be a bit of a waste of time....no offence!

I hope I can send it to the lab to find out how much more or less solenoids from the engine produced instead of OEM oil. because willall has one test with 10w60 already and I can't buy it anywhere.
