Synthetic Lubricants

[whw]

Anybody know the best oil change interval when using synthetic lubicants like Mobil One? The Lexus owners manual only mentions the normal interval of 7500 miles and severe duty interval of 5000 miles. Porsche recommends 12,000 miles with Mobil One for their vehicles. Surely, Lexus can't be that far off.

mm most synthetic oils are suggested at not too long after 5000 miles. i change around 6000-7000 because the car doesn't go through a lot of rough driving very often, so i let it sit longer.

synthetic oil and filter every 5,000 miles or every 4 months.

You can't go wrong.

use a good filter (Toyota, Mobil 1, K&N) that has a back-flow valve.

I use Mobil One and i change it out every 3500. I also want to show every one soemthing neat. I used a relocation kit from a supra twin turbo to make the oil filter easy to get to. Here is a picture.
