Just wondering what oil (5-30, 10-30, 10-40) most are running in their turbo street cars? I have a bone stock bottom end LQ4 with a 76mm turbo, making about 600whp, and I live in Ohio. What would be the best oil to run? Currently Im running Mobil 1 5w30.

Thanks for your help,
Anthony

I run Rotella T6 15 40 its cheap and has high zinc

 

I have searched here, and its all over the place. I just want a general "if stock bottom end, use this" or "if built, use this". When it all comes down to it, I just want a good oil for use in a stock motor with a turbo on it.

 

i like valvoline synthetic vr1 20w-50 on stock bottom end 4.8.

 

I would go with the Valvoline VR-1. Its a great oil and proven on many boosted vehicles.

 

I run the Valvoline Vr1 20 50 also

 

Most of the people I know run rotella t 15-40 in their boosted cars.

 

+1 Rotella 15/40

 

Where are u guys getting the rotella at?

 

Is the Rotella 15w40 synthetic?

 

Always bought mine at walmart they sell it in the big jug

 

If you want it to be. They sell rotella and Rotella T6. The T6 is synthetic

 

You will not find a answer like that.

Louis @ LG Motorsports has a great thread on oil in this section too.

 

I've been running the Rotella 15-40 for about 3 years now and bearings still look good

 

thanks

 

CAM2 here. High zinc formulation, and I run a mixture of 10/30 and 20/50 during the winter. Summer it's 100% 20/50.

 

I am running VR1 with 500 mile change intervals.

 

Holy crap! You do not like your money, do you?

 

Run the regular VR1 20-50 and no issues but thinking of switching to the synthetic.

 

Turbo cars need a slightly thicker oil due to oil temps. I get Mobil 1 5w 40 for free from where I work so that what I use.
