Hi,

According to my GMC olds 455manual I should be using sae 20w20 engine oil but it doesn't seem to exist, what's the appropriate equivalent (for New York winter Avg 30 degrees).

Here are my notes from the manual....

Only SE engine oil, single grade oils best, multigrade ie. sae 10w-30 or 10w-40 ok
Sae 5w-20 oils not rec for sustained high speeds
Sae 5w-30 oils may b used if extreme low temp anticipated.
Sae 30 = 40-120 degrees, sae 20w20 = 10-80deg, sae10w = -10-60deg

Thanks,
JP
