Have a 1973 Dart Swinger 318 63,000 orginal miles. When should the oil be changed? Been changing oil at 1000 miles.
Thanks. Where can you buy ZDDP additive?
No clue. My 408 is going roller cam setup, then I won't have to deal with it.
Advance Auto Parts stores have it in the Yellow bottles, adds Zinc to the oil.Thanks. Where can you buy ZDDP additive?
What do you guys think of this?
What do you guys think of this?
Southeastern part of PEI. Murray River. 11 miles from the Wood Island ferry.I use Joe Gibbs oil it's loaded with zinc..on a side note where are you in P.E.I. we vacation up there all the time..
Thanks. Using Penzoil 5W30. Think I will change it every 1500-2000 miles.Every 3000 km?
I routinely go 10,000 km in my daily drivers and just use 5W30 Penzoil,
Same oil in my '69 340 built to stock specs but it never gets much mileage,
so usually about every 3 years or so as long as it is clean.
FWIW.... Just be aware that a 15W50 full synthetic at cold temps (like below 40F) is going to be as thin as a 5W dino oil at those colder temps. The 'cold' temp viscosity of motor oils is measured at 104F and the oil's behavior at much colder temps can be quite different depending on the oil material. Pout them both out of the bottle at room temp and the lower viscosity of the full synthetic will be immediately obvious.I think that 15-50 is for supercars, late vetts take 0w-40
see that column with the phosphorus- that's what your are looking for
after break in and without really stiff springs I think 800- 900 works fine
Oil is constantly being re-formulated stay on top of it
