84 yota ex-cab

Has anyone tried the castrol high mileage oil? I am debating wether to use it or not.
thanks

Is it synthetic? If not, then I don't think it really matters. I think it is a little thicker so it doesn't make your truck leak as much (thats my guess anyway)...other than that, I can't see the oil being any different.

I tried it, nothing interesting to report. It didn't leak, but it doesn't leak with synthetic either.
