What are considered dangerous oil temps for oil? Im using 20w-50 Valvoline VR1.

 

your using 20w-50 on a turbo engine? why ?

 

If your using oem clearances than 20w-50 is to heavy.Continuous oil temps over over 270* will break down the oil pretty fast.Over 300* and the oil will fail.A rule of thumb is 30* over water temp.that usually puts it at about 210*.

 

Many road racers say their oil hits 240-250 at the most w/o any coolers, and don't have issues. Coolant over 220F is usually a bad idea, so the 30F rule seems to hold true.

Motor is stock.. So 20-50 is too heavy?

 

Not to tread jack. Now that its gettin hot out. Do you run heavier oil........10w40

 

Thats what I thought, 20-50 I heard was actually good for Hot summer days

 

can anyone chime in on how much diff oil temps are during winter, then summer...

i dont think its much, if any... but i have no idea

 

here straight from AMSOIL http://www.amsoil.com/frequent.aspx

 

i always run 10w-40 in my boosted cars, and depending on if its a crap motor ill run lucas as well in there.


i would get concerned if my oil was constantly running over 250ish

So I shouldnt be worried if mine are @ 230ish. When I start to do pulls on the freeway then it shoots up. Maybe Ill invest in an oil cooler...
