Track Day Oil Recommendation
What engine oil do you guys use for your WRX or STi for doing track day lapping?
I have a Stg. 2 STi and do track days in MSR Cresson, TX (Dallas/Ft.Worth Area) So far, for the past 2-3 years, I have been using Mobil 1 5W-40 Diesel Synthetic Truck Oil to protect my engine. Recently I figured out that Mobil 1 isn't grp IV oil anymore. There are better oils off the shelf at local Auto Parts out there for the price such as: German Castrol 0w-30 (as thick as 37 weight) Shell Rotella Full Synth 5W-40. (Off the shelf = local parts store) Is it really necessary to go w/ THICK 20W-50 on a Stg.2 STi which only laps every 30 mins session or so in a non competitive environment? I'm trying to find all around oil if available. Inputs from track day whore is appreciated..

I use Motul 8100 5w40 and it works great. Very minimal consumption, I usually end up adding half a quart or less over the course of a full weekend event. I had similar results with Motul 300V 5w40 but it wasn't worth more than twice the cost. When I was using Mobil 1 I was burning a lot of oil, now I won't go near that stuff. Although I know a lot of people that use it in Porsches, BMWs, etc. with very good results.

I use 15W-50 Mobil 1 and have been very happy. Doesn't eat oil at all and oil temps seem to be slightly lower.

I'll probably go back to 5W-30 in the winter, but honestly, I doubt the car will be out of the garage much at all anyway.

Cool, I might give a heavier weight a try next summer. At my power level now the 5w40 is fine but in the off season I'll be adding close to 100whp so everything will run a bit hotter on the track. I was a little worried that 15w50 was too heavy but maybe I'll switch to Motul 300V 15w50 for the summer.

i've been running Eneos 0w-50w for the past year and a half. car sees mostly track days, never any problems. of course, AZ. climate is different.
i just switched to Motul 300v 5w-40, so we'll see how that does. |

Motul 300V 5w-40 here, will get the UOA back from the 300V 5w-30 with ~4K miles and 50 minutes of lapping probably next week. This run of oil will have 81 autocross/ProSolo laps and ~6K miles
Should be sufficient for a trackday. If you need a place to get NASIOC deals on Motul, PM me |

I've been using the same with similar positive results like mav1c. Oil temps are steady and very little burn, car has ~30K. This is including SoCal summers.

I noticed my oil temps were about 10 degrees higher with Mobil 1 15w-50 than with the 5w-30. 5w-40 sounds like a good compromise.

I've run quite a few oils in my track car.
Castrol Syntec 5w50 Mobil 1 - 15w50 Valvoline Racing 20w50 Shell 15w40 (non synthetic) No issues with any of them. Car sees no street time at all. Oil changes every other event (roughly) -Duncan |

No more track car for me
I use German Castrol (BMW Long Life Approved) on my current car. I also use Shell Rotella T on both Saab 92X Aero and Triumph Sprint ST 1050 w/ Purolator Pure One Oil Filter (3.25" length PL14610 - about .75" longer than OE length) |

I use Rotella T in the NA rally car, it sees as much high RPM hot weather use as any track car plus all the dust of a rally car. good stuff.

Anyone using the Rotella T non-synthetic 15w40 on the track? Or just the synthetic 5w40?

I ran the non synthetic this last track weekend. I haven't sent the sample off to get checked though, so I can't really give you any data on how well it did.

Seriously, if you're dropping it every couple of engine hours, do you really think it matters? Moreover, I don't imagine you're firing it up and competing in really frigid conditions where a synthetic truly shines.
