Similar to another thread on this page, I am no longer able to find German Castrol at ANY of my local Autzone stores here in MD
I am now looking for an alternative that will allow for similar OCI's (~10K miles) and that can stand up to a bit of abuse.
I went to Walmart earlier today and found some Royal Purple 5w-30 and bought 5 quarts, but am now beginning to regret it given that I came up with more negative than positive search results for it on this site.
My question is, should I take the RP back and get something else?
I use a Honda S2000 Toyo Roki oil filter and with the GC at 10K OCI's, the engine would only burn about ~1/2 quart of oil or so (if that makes a difference).
I really don't want to have to order Amsoil, etc. but will do so if I have to.
So what do you guys think? RP? Pennzoil Platinum? M1? Also, what weight would you recommend for each in this application?
Thanks for the help!
