Should you Use Thicker Oils After Tuning & When Should you Change Fluids On a Tuned Supra?

[PontanB]

I haven't seen a full thread on this but please link it if it exist!

I am currently tuned to 441 whp & 599nm and my questions is should I switch the oils in the car to somethings else?
Transmission? differential? engine oil? (all factory fluids in the car as of now)

The car will be driven pretty hard and it will attend track days. So when should i change the fluids for optimal safety?

5W40 all day for a high boost turbo car.

Just one man's opinion.

Id do 5w30. Seems to be the sweet spot for stock turbo

I switched to Liquid Molly 5w30 and I swear the engine is more quite. I watched that 0w20 drain and I'm certain I've got bourbon thicker than that stuff.

I'm personally still using 0W-20 (Amsoil) on a stage 2 93 octane tune with a couple track days under my belt, no issues here. You'll probably have a new car by the time you need to change the tranny and diff fluid.

My plan is to keep my Supra for the rest of my life so i want it to last long

I’m running the same oil too and the car loves it.

Yes and yes….tuned or not 5w-30 is the better oil viscosity. Why you ask? Because @zrk said so damn it. ?

Yeah- live and die by the LiquiMoly Special Tec

Also jumping on the 5w-30 Liquid Moly hype train. Switched to it at 5k last year, and the car just felt nicer to drive.

Is there a reason liquid Moly special tec LL 5W30 is the best for tuned Supras?

It's german oil. German oil works best with german cars i guess lol. It's a long time remedy for BMW's. I'm also on 5W-30 Special Tec too. My car has only seen Special Tec since i did my first oil change at 1000 miles. Thinking about giving LiquiMoly MolyGen New Gen 5W-30 a try though, heard its the new thing on the block. ??‍
