I purchased a 00 Tacoma 2.4 new in 2000. Put 187k on it in 4 years. Used M1 5/10w30 until it was sold. The engine ran like a top, never consumed a drop and the emissions read lower than average. In 00, I was not quite the most savvy when it came to oil and used to change it out at 3k. If I had a 2.4 now, I'd run 8-10k OCI's.
