If you are to choose an oil rating, which one will will you use?

Hey guys, need your expert advice on this one.

Which oil viscosity will you use for racing or even just a fast road set up engine(like slightly modified engines), SAE 0w40 or SAE 10w60?

any inputs would be very much appreciated!

10w60? That's way too thick.

For an old engine, where you're not sure of the tolerances, 20w50 is safe... for newer performance engines, you'd go for 0w20 or 10w30... the smaller the range (the difference between the two numbers), the less additives in the oil and the better its resistance to breakdown... in fact, you can use straight 30 or straight 40 oil for the racetrack, but they're not recommended for road use.

10w30 or 10w40 is okay for daily use. 20w50 for older engines... all depending on the engine in particular. Engine safety first before extra performance. ;)

10W-30 if your engine can take it.

Some engines that is geared to maximize fuel consumption can take in 5W-30 too.

not the 10w60 definitely.

what engine is it for? what are the mods? if it's built what clearances did you use?

we use Royal Purple OR Valvoline synthetic 10W30 & 15W50 for our race cars. and sometimes we use Redline synthetic oil.

aite, peace.

I was just actually curious because ive seen some people using MOTUL 300V Le Mans 20W60 during hillclimb events and some races in BRC. 20W60 is even thicker Although most of them use it on older engines. I saw it being used on a Porsche 911.

i was just wondering if they get really better protection from it
