what oil should i use in my 302?

I hear 5-50
I hear 20-50
full synthetic
Purple Royle

any advice?

 

I just run 10w30. No issues. Just a clunky old 5.0 Its not very fussy.

 

10w-40 in EVERYTHING!

 

20-50 Castrol

 

IT does depend on your climate at the time though. Mine is only a summer car up here but the weather gets cold in OCT before it goes away in Nov.

 

Is the motor stock? What are your bearing clearances? How do you use the car?

 

They have some new stuff now called multi-viscocity motor oil, should be on the shelves soon. LOL

 

Oil Viscosity

I run 10-30 syn. blend in my slightly modified 302 w/ AC in summer - no issues.

 

I'm real picky about my oil. Usually use 10-30 in my street cars. Unless all I have is 10-40. Or an extra 30 wt lying around. Last time I changed oil in my race only Grabber I had 5 qts of 5-30 synthetic and 3 qts of 5-30 regular oil, so I mixed em together.

 

It is better to run the car WITH oil, than without.

That being said, it pretty much doesn't matter what oil is in there, as long as you HAVE oil in there.

I would steer clear of Extra Virgin Olive Oil...

But again, that would be better than NOTHING!!!

 

smell good as it burnt up too

 

I use Mobil 1 15W-50 in the worn out 302 in the Comet. Holds better oil pressure that 10w-40 since it's thicker of course. 10W-30 High mileage goes in the 170 in the Maverick.

 

20/50 on a high milage motor..

 

I like Brad Penn 10w-30 in an everyday driver and 20w-50 in my nitrous motors.
