You are, of course. However, a 3000 mile change interval is STUPID with modern oils, and any engine that truly REQUIRES it is a piss-poor design and unworthy of being on the market. My 1966 V8, my '69 V8, my 73 V8, and my 93 V6 engines ALL have passed 160,000 miles (241,000 for the 93,
430,0000 for the 73!) with 7000+ mile change intervals. 1973 American engine technology isn't THAT much better than modern Japanese engine technology! ;) End of discussion.I agree when it comes to suing Toyota or doing something like that. They covered their bases just fine, and so the only real recourse people have is to quit buying Toyotas until they can demonstrate that the problem is well and truly fixed.
No, but lots of them, including GM, allow much longer drain intervals and have oil-monitoring systems.
This may sound like I'm ripping Toyota a new one, but I'm really not. They've made some incredibly reliable engines over the years. My gut feeling is that they tried something to reduce emissions or increase efficiency, and it had an unwanted side-effect. Same thing for the Chrysler 2.7 v6, in my opinion. Chrysler is my brand of choice most of the time, but I won't buy a 2.7 for anything! It happens to all carmakers. What I can't understand or abide is the attitude that " can do NO wrong! It must be the owners!"
