I have 221xxx miles on my car I use synthetic oil. I burn through oil to say the least. Example I changed my oil yesterday and drained out less than 2 quarts. Should I just go back to Dino oil? I only had 100 miles off till I hit 3000 between changes plus I added 1 quart. Maybe the synthetic Burns faster?I live in FL
So its hot out...maybe thicker oil? Anyone experience major oil burn? What oil works best 7afe?

5W-30.

Yeah, suggest a really thin oil when he's burning oil...

Use a 10w30 or 10w40. You're in a climate that is always above freezing. Our cars take a higher viscosity oil and over the years, especially with your case, since you're burning, you need to raise the oil thickness. In the summer with that many miles, I would be running a 10w40.

20w50 is what I use. Being you're in the south as well, you'll be fine.

i'd go with this.

20w 50w is a bit extreme? Especially on start UPS, wouldn't that do more damage than good?

Not when the temperature isnt going to drop below 70°, 20W-50 or 10W-40 is what Toyota recommends for this temperature range

20w50 is what was used and, was recommended to keep using, by the ASE Toyota master technician that owned it before me.

I two have the same issue with burning oil can I still use 20-50 up North in the summer months?

I always go with semi-synthetic because our cars are older. But ill go with either 10/30 or 10/40 if I were you.

Thanks I have been using 10-40 but the one for high milleage my car has somewhere along the lines of 300,000 miles on it.

All high mileage oils are semi synthetic. They have additives (synthetic) that add to engine life and extend the life of gaskets and seals.

Auto-Rx. I had low compression in my middle cylinders. Evened it right out. Supposed to free the rings.

Synthetic shouldn't burn faster. It is much more resilient to burning unless its blowing pass the rings pretty bad.

In wondering if I jump back to semi synthetic, will it help stop burning past the piston rings as bad?

It should

Anyone have experince in this?

I don't really think synthetic will help stop the oil passing the rings. I had that problem before I had my engine rebuilt and tried everything. I concluded that I just wasted money on more costly synthetic oil and instead tried Lucas oil additive which does offer a guarantee to stop oil leaks and whatnot. I think that helped because I remember having to add less oil here and there. Bottom line though man, just get regular high mileage oil and keep on it by adding oil when needed. Don't waste your money on synthetic now. If you can, just get it rebuilt or swap it for another engine.
