Motul 300V 5w-40 or 10w-40.

Change every 3 event, no daily.

 

I use Napa Gold. Mainly because I get them at the shop for free, but they have also shown to be a decent filter. Anyway check this link out for more information on filters.

Yeah it's readily available. It is made by Torco for us.

havent done any UOA's but ive used Redline, Motul 300V, Amsoil, Neo and the only oil that doesnt burn in my motor is Pennzoil Ultra... a group iii.

 

Amsoil 10w-30 for me. Change oil every 2-3 track days at most, with some highway/city driving in between.

 

Unless a w30 oil is actually breaking down, then your engine will run cooler with a w30 oil than a w40 or especially a w50. Thicker oils generate more heat. This according to the Redline tech rep.

 

Thicker viscosity oils will indeed cause a rise in engine temperatures but you would likely never know it based on water temperatures alone (going up to an SAE40 anyway) There will be more friction with the oil film itself and therefore you will generate more heat. The idea is that the thicker fluids MAY provide more protection under hard track use but I have yet to see any real evidence to support that for the F20, F22. That said, I don't believe you are doing any harm and if it gives you piece of mind then go for it.

For the S2000, thinner may work just as well. Check out the first UOA reports on my S2000. When I first bought the car the oil in it was 5w-20, I used this for something like 50 autocross runs and always ran it to redline. Since then I have switched to an SAE30 and I will sample it after we get some more events on the car. I am tempted to try a 0w-20 around early-mid summer and see how it looks.

 

Bringing this back up from the dead since it hasn't been updated in 9 years, lol.

So, in the year 2021, what's the go-to engine oil (full synthetic) and weight for those of us who track our S2000s?

 

This guy did a huge test on what's the best oil

Amsoil won

Pennzoil is 2ed best and under 20 bucks at wallmart

I use Pennzoil I have 0 issues

 

Is anyone in this section of the forum worried about resource conserving 5w30?
