Changing the motor oil in my CJ-7, stock 304 V-8 with about 38k original miles. Vehicle may see about 750 miles/year. Which oil and why?
Choices in my stash are:
1) Smitty's SuperS 5W-30 syn/blend GF-5/SN
2) Mobil Super 10W-30 GF-5/SN
3) Valvoline Syn Power 5W-30 GF-5/SN/Dexos-1
4) M1 EP 10W-30 GF-5/SN
Please let me know soon, want to knock this out before the Masters coverage starts. TIA
