Ok, since I got my daily drive a year ago (89 4x4 Toyota Truck ) I put minimal miles on my R but drive it at least once a week. I’ve only put about 2,0000 or 3,000 miles in the last year and I do an oil change at the dealer every 3-4 months, they top off the fluids and use the oil I bring, Mobil 1 Syn. I also rotated the tires and did an alignment, which I plan to do once a year if I drive less than 4,000 miles a year. I try to wash it once a week, detail the inside once a year, and buff and put a paint sealer once a year. What other things would you guys suggested to keep the engine in good shape? It has about 70,XXX miles on it and I did the 60K about 1.5 years ago.
