Big power boosted guys what weight oil

Supercharger doesn't change the fact the engine was designed for 5W20 in normal driving applications. I use 5W40 on a road course but on the street, even if I had a super-duper-de-fabulous-charger I'd run Penn Ultra Plat 5W20 without a worry.

Everything I read tells me it's one of the best motor oil you can run at this time...

Penz Ult Plat is what I normally run. Had some spare MC stuff I wanted to get rid off.

making 804 whp. i run 0w20 made by mobil. specific for toyotas. every 2500 miles. oil is free at the dealer. boosted for 10k miles just checked compression when i did plugs havent was all consistent. 36k miles on car total. does not burn a lick of oil.

Big power? I dunno, but run Penn Plat 5W-30

I'd like to try the ultra plat but no walmarts near me carry it. Everywhere else is almost the price at what I can get Amsoil for.

Mobile 1 5w20 Ford Racing Oil Filter...I have always ran M1 irrespective of the car and cannot say i have ever had oil related issues with it (20 years and multiple platforms of racing).

Whatever the manufacture calls for I run with it being synthetic.Only way I might consider running something different is if I was doing road course racing,and even then i.would use it only for whatever event I was running.

ditto

I have been running Amsoil Signature Series since getting the car new in early 2015. 5w-20 for 3500 miles. Switched to 5w-30 when going boosted...at 18k now. No issues and doesn't use a drop.

5w20 Castrol, compression was golden. I do change my oil every 2500 or so (which is basically a years worth of driving for me).

Motorcraft Full Synthetic 5W50 as recommended by my shop and engine builder. When I was at your power level I used Royal Purple 5W20 HPS.

I am running 655RWHP after the work Brenspeed did to my car this spring. They told me to use Motorcraft Full Synthetic 5W50 as well.

Pennzoil "Ultra Platinum" and Quaker State "Ultimate Durability" are different brandings of the same refinery output from SOPUS (Shell).

I believe I'm only around 700whp but I stick to 5W-20.

The variable cam timing components work based on oil and they are designed for 5W-20 so that's what I stick with.
