My 99 has 253K miles and the PO gave me all the records. I’m up to date on all maintinance...but now I need to get my first oil change. Ive had it about 5K miles and doing a 1K mile road trip this weekend. It has conventional, as it was changed at the Ford Dealer I bought it from. Oil (all fluids) was checked by LC mechanic a couple weeks ago and he said it was good. I’m thinking High Mileage Mobil 1 with a M1 filter based on the what I’ve read here. Ive had good experience at Toyota dealers using their standard oil/filter. Does the dealer to M1 Synthetic Oil/Filter? Is Toyota Synthetic Oil/Filter OK? Should I find a Mobil 1 Quick Lube around? Or, should I let it go as mechanic said oil is still good? How can you look forward to a 1K mile Road Trip in a 19 year old vehicle? Simple, do it in a Land Cruiser! I’ve only put 5K on mine but look for every opportunity to drive it. Thoughts?
