quote:I've been told by several Toyota mechanics that it takes between 10-15,000 miles for a Toyota engine to get fully broken in. With my '03 2.7L 4x4 Tacoma, after changing my oil and filter at 500, 1000, 2500, and 5000 miles, I switched over to synthetic, Mobil One 5-30 wt. From that point on, I've been changing my oil/filter every 3,000 miles. I've also been using the Lexus 90915-20004 oil filter. Today my truck just turned 10,000 miles on the odometer on a trip. On my trip, I got 200 miles on half a tank of gas, doing 70 mph, which is approx. 25 mpg. This is the best I've gotten so far w/it. I personally believe the first oil change is the most important. Not only have you the metal particles from the initial engine break in, but possible metal shavings and casting sand that are left over from the engine's manufacturing process. I just bought a brand new Harley today, and it's going to go through the same oil and filter change process as my truck went through.
Hi, I just picked up an 04 Tacoma 4X4 with a 3.4 V6, does anybody have an oil recommendation for this vehicle. Can I switch oils right away? I was considering Mobil 1 5W-40. Would it work well in this application? Thanks.
quote:Again, the first one being the most important, thus my 500 mile, w/it's, essentially, flushing the engine. At 500 miles, the engine is still breaking in, thus my 1000 mile. The 2500 to 3000 oil change is the normal recommended first oil change, at least w/the dealerships.
P.S. Changing oil 4 times during 5000 miles like GoHack did is just a waste of resources - doesn't help anything. (But some people have their own "scientific" approach).
quote:Shouldn't that be the other way around, w/6-10K for the Dino and 8-12K for the synthetic? The synthetic provides less wear, and thus a longer break in.
I read a study once and it indicated that it takes any car about 8-12k miles to completely break in with DINO oil. With synthetics complete break in interval is about 6-10k miles.
