OK guys. I need serious help. I have an oil problem. The dealer in Indiana that I used to get my Amsoil from , was a Napa store, I stoped in there and he said he was haveing a hard time getting rid of the Amsoil and 5 qts of Red Line 75w90 gear oil. So what do you think I did? He sold me some Amsoil 2000 0w30, the 35,000 mile oil for $3.75 a qt. I bought a new K&N oil filter and away I go, This was 2 days ago. I have to say, this oil has had NO problems with starting or noise in these cold Mi winters. Only been in the teens, but hey how could I pass up this deal? Now, should I buy the Red Line gear oil? He said around $4.50 for this. I always heard this was great gear oil. GUys I know it has only been a couple days. But does anyone else have the Amsoil 0w30 in their vehicle? Great oil!
