Vet I use has a 1967 Tr4.Had engine rebuilt never drove and put in dry storage for 5 years.Anyhow just got MORE work done and auto is back on the streets.What WEIGHT OIL does this car need.He has no clue.Runs great,smokes some and holds 7qts?
I'd start with 15-40 delo for the moly.
You can work your way thicker. For cheaper but nice moly - 10-40 Chevron Supreme or a mix with 20-50 Chevron Supreme. Or the same mix with a good sale SM like Pennzoil, Castrol, Havoline.
All the engish stuff had 20-50 listed but I don't think you need it other than for smoke.
Hi,My first ride in '66 was a '64 TR-4.As I recall(or don't)I put straight 30wt or 10w40 or whatever Castrol was available.The old 4 banger was an english tractor motor, me thinks? What a blast racing my friend in his '57 Chevy at over 100mph.I won with one hand on the wheel. He was all but out of control on that day.What memories!!
