I know this truck
That oil doesn't have enough ZDDP to protect the cam lobes from wearing out . Are you adding ZDDP separately?
7 hours I won't get back. That 60 has been hit hard in the drivers side and had a lot of body work. Nothing on left side lines up, hood, fender, both doors.
Right side is beautiful. Can't believe Eric and I rode all that way for that.
So what oil does have enough ZDDP?
You can go buy ZDDP additives but you really don't know how much you are adding to reach to proper level. My math says you had to buy several bottles of this stuff to just get the needle to move on ZDDP content, especially engines with big oil pans like a Crusier. Not worth it when you can buy an oil with it already mixed appropriately.It's a zinc additive you can buy at AutoZone. Old conventional oils had lots of zinc in them. The newer conventionals and synthetics phased it out for regulatory reasons.
Why would 20w/50 Dino not have it and why would the 2F care?
Wonder if the Lucas has it?
@Texican been preaching Castrol 20/50 long as I've known him
Ugh- When I went to look at the 62 he was selling he wanted to show me his 60, too. It was in the garage with the drivers side by the wall, so I never even would have guessed that side wasn't as perfect as the rest of the truck. He was real proud of it and it looked spotless inside, engine compartment, and out. Sorry if I put you on a wild goose chase.
So 15w-50 Mobile 1 Synthetic?
Is that "thick" like the 20w-50? That's what I'm going for. I've truly never heard of ZDDP or the lack of it.
31 years and 235,000 miles who knows if this motor has ever had oil with ZDDP in all that time.
Just sounds like Mud goobily-goop but hey, you are the rocket scientist
