I agree throwing $$$ away that way.

Even just another 1000 miles on synthetic would warrant using full synthetic.

 

Autozone had 5 qts Mobil 1 5w-20 and a Mobil 1 syn filter for $27.00 two months back. Still had to buy 2 xtra qts but the filter ends up being free. Good deal for the DIYer. First post by the way

 

Yeah I just bought the Mobil 1 offer from Autozone. Tough offer to beat. Better oil, better filter.

I had 2qts of M1 0w-20 given to me from my cousin. He works for PepBoys in Philly. So the 5qt kit was perfect.

 

Mobil 1 10w30 stock Mopar filter every 5k! Factory 3k oil changes are a waste of the worlds natural resources and a Dealer scam!

 

Mobil 1 all the way.

 

Pennzoil Synthetic 5-W-30 and a Fram Xtended Guard filter@ 99K. I don't know much about what has been in there before now (just bought it from the DEA) , but I will use good stuff from now on. As for the change interval, I will use some compromise between 3 and 10K based on the synthetic, the extended life filter, the conditions and the oil appearance after some miles go by. If I have lots of carbon contamination (from blow-by), the change will come sooner. We'll see in a couple of thousand. Oh, I used 7.5 quarts including filter.

 

The truck has never seen anything other than Mobil 1 5w-30 full syn for all 130,000 miles of its life.

 

Amsoil with 1 Quart of Lucas Stabilizer

 

Which oil from amsoil are you using XL, ASL, SSO? Whichever one it is the stabilizer isn't necessary.

 

I'm using Xl. Thanks for the info. I didn't know that the stabilizer wasn't necessary
