I have a 2007 tacoma with 2.7 4cyl 5spd. It has 265000 miles. I bought it at 52000 and have always used full synthetic oil, mostly 5W30. I change the oil/filter every 7500 or so and check the level regularly and add when needed.
It usually uses about a quart to 1.5qt between oil changes and has no noticeable leaks. And I do not see any black smoke and it always passes emissions.
I get 24-25mpg at 65mph.
My question is. Should I switch to "high mileage" full synthetic or stick to what has been working? I would hate to cause a leak because of something may be "cleaned" or cause things to swell and start to leak. Or get lower gas mileage.
PS. I am on the original clutch, When I finally do replace it should I replace the flywheel or just resurface? I have heard pros and cons for both. Mostly there may be "hairline fractures" in the flywheel that will not show when resurfaced.
