so an oil change is fast approaching and it's time for me to go synthetic since i'm gonna be turning 40k on the old odometer. ordering online doesn't work for me since i seem to procrastinate. i have two options here at the auto store that i can buy. valvoline premium blue and mobil 1. give me your thoughts on these oils pros and cons, likes and dislikes. any input is greatly appreciated.

 

out of those 2 I would go mobil 1

 

I don't believe that the Valvoline Premium Blue is synthetic.

 

i think the premium blue is only a semi synthetic...

 

that could be i'll have to check on that again. i do know the valvoline has a cummins endorsed emblem on it though.

 

Any thoughts on Valvoline Premium Blue Extreme?

 

I'd probably go mobil 1

 

so far i hear mobil 1 and it is like 2 1/2 bucks cheaper per gallon. this is good news thanks for everyone's input.

 

Walmart carries Rotella T 5-40 synthetic, just a thought

 

Just saw at wal mart today oil called Del Vac by mobil 1, I didn't get a chance to look at it closely. Does anyone use this type oil?
