I know, there’s a oil and lube thread, but it doesn’t seem to get a lot of viewers, and I want to change the oil in my new-to-me 2000 Trail Boss 325 4×2 before I take it on vacation this weekend. Wally World has Mobil 1 0w40 (it says ‘For European Cars – I’m guessing that doesn’t make a difference), and Advance Auto has Castrol 5w50 full synth. Also, for the transmission – can I use Valvoline 80w90 instead of AGL? I’d be fine with using the Polaris lubes, but I can’t find any in my rural area, so I need to substitute, at least this time. Again, sorry for posting this in the maintenance thread (it really is kind of maintenance!), I really appreciate any advice and opinions.
