When i was talking to ray from 'raylar'after i had the cam installed, I was asking about oil/fuel.. he told me he never understood wh gm says to put 5/30 in the 8.1 he told me to run 15/40.
Definitly 8.1 , Ive also had both and the gas wasnt much better at all in the 6.0. both my 8.1 trucks dont use much oil.. Its definitly less then 1 qt in 3000 miles. The guys that knock the 8.1 have never driven or owned one! the only thing you could complain about is the mileage which again isnt much worse then the 6.0,s Its one of the best motors gm ever made, My most recent one is in an 04 silverado with 243,000 miles, It fires rite up and runs like a champ!
Can you send me a pm and just give me some quick tips how to add and up-load pics to the forum..Exmp- If I take a pic on my cell phone and want to add it to a thread..How do i do that? does it have to go thru 'tapatalk'? Thanks
Nice. That's my favorite price.
Chris, congrats on the 6.0, I loved my '07 vmax. Don't eat that whole burrito, you may blow a different gasket...
HA!!! LOL..
+1,!! A fresh fuel filter is always a good start..And regardless if it was the problem or not..Its new and one less thing to worry about!
But the cats are important..Ive seen cats after 230,000 miles and they looked new. Also seen cats with 50,000 miles and 3/4 clogged,
Many things can get them shitty, Bad fuel, exhaust leak for a long period of time,etc...
