engine oil capacity and type

I see engine oil capacity varies somewhat from year to year for the 6.2. I just installed a '90 6.2 motor in my 'burb and put 7 quarts in yet the dip stick still reads low. I don't want to overfill, how many quarts does it take? I'm using SAE 30 oil too which is what I used to put in my '86 6.2 motor, is this fine?

Could be different dipstick / oil pan configurations for 2WD / 4WD and pickups vs. Blazers / Suburbans? My '89 takes 7 quarts exactly and dipstick reads full.

As far as oil, I run 15W40 year round. I know the cap and the owner's manual says SAE30 but a) that was back when CD-rated oil was the best available, and we're now at CJ-4... and b) 15W40 is specified for the later 6.5 turbo engines and I couldn't see too many mechanical differences between 6.2 and 6.5 that would necessitate the straight-weight in the 6.2...

SAE 30 may be good with high ambient temperatures --- I wanted to try it, but I don't know, 15W40 seems to work just fine ...

It takes almost two gallons for an oil change. I buy the oil in two gallon bottles, fill the oil filter before installing it and pour the rest of it in, leaving about 1/2 quart in the 2nd bottle. It's eventually a bit much, but the engine seems to like it better when the oil level is close to/at the full marker.

Oil Usage

The post on the dip stick may be correct. did you purchase the engine complete or did you transfer the dip stick from another engine?

As for the oil I have found that AMSOIL Synthetic is the best. they have a new CJ-4 (15W40) which is backward compatable with older engines as well. It will give you more MPG and protect the engine better. It also give you the opportunity to extend the oil change intervals by 3 times or more.

my 87 3/4 ton takes 7 quarts on the dot and its all stock atm, i would be running a 15w40 over the 30 weight, it will be better in hotter weather, and also colder weather.
