No problem, I've seen the tests on dino oil lholding up well over 7K miles. Also some cars are running up to 10K miles on dino oil per manufacturer recommendation.Originally Posted by kickin8

I myself am on the same boat as some of the people asking questions on this thread. I would like to use Mobil 1 in my recently purchased 2008 IS 350, but am wondering how to go about longer oil changes.
caymandive's suggestion here (and Knightshade's suggestion on my.is) are how I will probably go:

I've never done my own oil change before but will probably start now. Thanks brel523 for this:Originally Posted by caymandive
#2. Change the filter only and you will lose some oil with it. Just top it off when you install the new filter.

It's really easier than it looks/sounds and WAY cheaper than the dealer.

Ah, thanks for this. I had always wondered why you couldn't just get a better filter to go longer with the Mobil 1 oil's extended life. Originally Posted by lobuxracer

I use mobile 1 extended filters...

Since I would have to drive up on ramps, get under car, remove oil filter and let drain, put it all back together. Why wouldn't I just change the oil while I'm under there(other than cost of oil)? Removing one more bolt is a breeze and I already have oil container there.
I guess I'm saying, if I go to all that trouble to change the filter at 5k, I mind as well change the oil. Other than cost of oil, am I missing something?

That cost of oil is pretty significant though right? You're saving $40 or so would be my guess - how many quarts of Mobil 1 would you need?Originally Posted by brel523

Lexus recommends those viscosities not just for cold start performance, but also for better fuel economy. As I recall, the language in the owner's manual says that 10W-30 can be used if 5W-30 isn't available, but they recommend switching back at the next change. From the Blackstone UOA reports that folks have posted, it doesn't look like there is any need to fear depleting the viscosity improvers in the 5W-30 and 5W-20 grades even with extended drain intervals.
