Oil Recommendation for 1965 Maserati Sebring (I6 w/Lucas Injection)

[Onassis91]

Does anyone have a type/viscosity recommendation for a 1965 Maserati Sebring w/Tipo AM101, Lucas injected I6? I’m not sure about the cars service history, but the climate is Central California.

Thank you!

A quick Google search showed that those originally specified 50 weight oil. I would probably use Mobil 1 15w50, or if you wanted to stick with a conventional oil, then Valvoline 20w50 VR1 would be a reasonable choice.

Had a 107 4Porte and Maserati techs suggested 20W50.

15/50 or 20/50 nothing thinner- these are old engines - don't run late model thin oil

any 229.5 oil

actual spec sheet

Good find, 2EHA, though it doesn't change the appropriateness of what's been suggested so far. I'm confident that any modern 50w oil is going to be superior to any sort of 60's Italian racing oil brands which would have still used Group I solvent refined base stocks and ancient technology in terms of additive packs.

yes, but no VII with the associated lower HTHS, so maybe a 5W-50 is a bad idea though on the other hand the car likely isn't run hard anymore...

I’m thinking 15W-50 M1.

20w50 be my pick.. castrol or shell

15W-40 in either Delo/Delvac/Rotella flavors or the “classic” high-zinc 20W-50s such as Castrol GTX Classic or Kendall GT-1 Performance. M1 15W-50 wouldn’t be a bad choice either.
