Synthetic oil or not??
I have just recently acquired my 2000 lexus gs300. I just hit 90k and reading about the 90k service. I went for an oil change the other day at grease monkey and inquired about synthetic. They said with my mileage now, it wouldnt really make a difference and that it usually helps when you have been using from the beginning. What are your thoughts? Should I stay with regular oil or go with syntho?? 40 bucks vs. 80 bucks...
Thanks!
Thanks!

synthetic baby. i used synthetic in my high mileage cars (100k Miata, 200k Volvo) and also added Lucas gear oil to help the oil viscosity. i haven't changed my GS's oil yet (i've only had it for about 3000 miles anyway) but it's on the to-do list soon. i plan on using synthetic.

What's your oil change mileage interval? If you're old-school, a typical driver and change every 3K then it really doesn't matter - but good waste of natural resource though.
But if you change between 4K to 6K or 2X a year, then might as well go with synthetic.
Like you, I have the same car with 43K miles. And personally I run Royal Purple.

the new synthetic formulas today are meant to be compatible with conventional oil, so you should have no worries. this was a problem back in the old days when it was still fairly new.

i dont usually rev my engine that high, i used synthetic on my honda with a vtec, but not for my lexus. i change my oil every 3k anyways synthetic or not. i dont think gas mileage will change just cuz u use synthetic oil, mostly in ur head. it's good enough if u just change every 3k
