Ditto. I’ve been to many oil company workshops over the years and the advise from the oil companies is “follow the manufacture.” My local service place once said, “we don’t recommend the base oil change (Valvoline). It’s only good for 1500 miles. So, I called Valvoline right then and there. They confirmed that any of their current oils will meet or exceed the manufacturer recommended intervals. The dealer no longer uses the 1500 mile line to up sell the oil changes. I personally use synthetic oil and follow the trucks recommended change interval.When my truck tells me too....
I believe it's standard dyno oil (manual tells which to use but it is not really clear what oil comes in the truck from the factory).is the factory fill synthetic for the 5.7?
Ok, but this is not an old-school hot rod. It is a modern, computer-monitored, state-of-the-art engineering marvel with really tight tolerances, which tells you exactly when you should do this.Mine is at 972 miles right now and I have an oil change scheduled for 2:30pm today. Should be just over 1000 mile by then as work is 19 miles from my house 1 way.
As an old school hot rodder, it just goes against my nature to leave original oil in a vehicle past 1000 miles. I don't care what the manual says. I want this engine to last me...
After this, every 6000 with synthetic is my plan.
First oil change after 500 miles (typical “break in” period for motors (old school rules). I do it early since the surfaces are still mating to each other and there is usually a fair amount of metal shavings I don’t want floating around. Then I’ll change again at 1,500 miles just to make sure she’s good and ready. After that I go to a 3-5k span, depending on what kind of driving I’ve been doing. I’ll do it more often if it’s been heavy on the off-road adventures as well.How many miles are you guys doing your first oil changes at?
I second this, but to each his ownOk, but this is not an old-school hot rod. It is a modern, computer-monitored, state-of-the-art engineering marvel with really tight tolerances, which tells you exactly when you should do this.
