Right now I'm running Mobile 1 Synthetic 10w-30, but I want something thicker to up the pressure a couple pounds and get rid of a very mild lifter tick. It's been getting really hot up her (around 105 the last week or so) and I think the oil is just too thin to be good for the engine. I was thinking maybe something like a 20w-40. Can anyone reccomend a good summertime oil?

Thanks,
-Ryan

Edit: The car has 95,000 miles on it and I baby it when I drive it, with the occasional stab here and there if I'm the mood (rarely heh)

Whats the oil pressure like?

CamaroZBoy

little above 50 pounds prolly maybe a little more then once u cruise around a while at low rpms it will slowly come down a little.

Ryan's LT1

At idle?!!? DAMN... I idle at about 15-17... I'm changing my oil SOON heh.

CamaroZBoy

at idle its lower as it warms up...prolly like 30 something....im not really sure, those electronic gauges arent to good.

Ryan's LT1

Yeah, but thats almost double what I have now. I'd feel alot better if thats where it was. Sometimes it gets about 40 degrees here, is that too cold for 20w-50 castrol? Also, is that a synthetic oil?

CamaroZBoy

nah it will warm up...and when it does it will be good for it...

Alright cool, I think i'll definately go with a heavier oil for sure then. Thanks for the info.

20-50 is a bit too far, the M1 5w-30 and 10w30 run particularly thin, if you want to use Mobil try the truck and SUV 0w-40, another great choice would be Castrol Syntec that specifically says 'Made in Germany" on the back and in a 0w-30, that might just be the ultimate LT1 oil if you can find it. If you don't like those choices just use almost any other 5w or 10w-30 syn. or dino because it will be thicker than the M1.

20W-50W will be fine until it gets to 32*F,then maybe 10W-30W.

Ryan's LT1

It rarely ever hits 32*F here ever, and if it does then its too cold for me to go outside anyways. I'm planning on changing the oil tomorrow and then again in novemeber when it will start to get cold, and i will go back to 10w-30 for the winter.

Thanks for all the great info.

Read up on some things and came across M1 15w-50. Sound like a good choice or should I go with something better? Remember I'm looking for more pressure when hot at idle.

Yea lived in Los Angeles for 7 years,ya get frost 1-2 times a year.
Good choice on the oil.15-50 is fine.

Cool, thanks.
