I just dumped it after 3k in my silverado. was quiet with the 10w30m1 hm. that oil did seem to make the truck a little less responsive than the 5w30 maxlife blend though. If i ever run it again i think i will cut it with a quart or 2 of the m1 0w20 wich i think is also mostly pao.
some people think regular mobil1 is missing a big thing that I think mobil1 hm 10w30 has in it, Gp IV basestock. After talking to the mobil 800 number and reading the spec's I think the hm 10w30 is better oil. IMHO
Brian, I started using hm oils in my 2000 silverado. The first one i tried was the maxlife 5w30 blend. To my shock i started get the best gas mileage I have ever gotten with that truck. I know that the oil should be thicker and cause mileage loss, but for some reason it gives better mileage. I...

I am starting to think that also.

I am starting to think the regular adbv's in most filters will not last for a 5k run without leaking. I noticed on my 01 impala with 3.8 and with the supertech or ac delco filter it starts making noise at startup around 2-3k. Just for the heck of it i put a new oil filter on and did not change...
I ran all three in my 1999 7.3 powerstroke with a stout dp tune on it. the delo gave me the lowest wear numbers. It gave me better uoa's than delvac1 also. I think delo is maybe the best or one of the best dino oils ever made IMHO
