Switched to Syn now losing oil
I just switched to synthetic RP 10w30 about 1500 miles ago and this morning the low oil light came on and I was about 1.5-2 qts low. Would this happen from switching to syn from dino? Right after the oil change i hollowed out my cats and had the car tuned, would this have affected this? It has 61500 on the clock.
Thanks,
Chris

Was your car 'leaking' or 'burning' the oil? I have never had a car 'leak' after switching to synthetic, but my Camaro does seem to drink a little oil when driving around a high rpm's for a while. It does not drink any oil when driving it normally. Were you beating on your car after you did these mod's to it?

Would a different synthetic solve it, like GC if I could find it? Should I switch to a thicker oil? I live in Houston so it gets pretty hot here. I did have it tuned on the street the week after I switched it. I did not notice it before losing oil. It is not leaking anywhere I can see.
Thanks again,
Chris

I'm using Mobil, and I hate how thin it is... like water. Now my engine has a light tap to it, although it's barely noticable over the heavy cam. I plan to change to a thicker oil. GC is out of the question- I can't find any of the good stuff around here. What WEIGHT oil is best? Something that has ***** to it.

My car had 10-40 dino in it when I bought it and used no oil before the 3000k change. Switched to a 0-30 syn and it used quart every 2000k. Switched to GC and it cut that usage in half. If you cant find GC, Mobil 1 0-40 or Castrol Belgium 5-40 have the specs that should help cut down that usage.

Every one of these threads has people struggling to live with synthetic oil for different reasons. I switched briefly in my LS-1, the cold start noises were much worse. I went back to regular oil.
On my previous car, A Buick GN, every says run synthetic to save the turbo. Those cars leak from everywhere. I switched to regular oil and the leaking went WAY down. Its not a myth, synthetic really does affect leaks.
If it causes you problems, just buy a good regular oil. As long as it meets SAE specs you should be fine.

LS1's will use some oil if you beat on them a bunch...
Try an experiment out, Drive you car for one week without revving it up a bunch and then see how much oil you used that week.
Hint: When my wife drives my car, it uses NO oil. When I drive it, I can lose a 1/2 quart in an hour or two (with me beating on it the whole time). I have run the Castrol Syntec from the first day it came off the car lot.
Post back what happens if you try this idea out...
Switching to synthetic will not make your car leak, BUT, I have heard that the Mobil One was a thin oil... Maybe switching brands might help some.
Do a search on some of Patman's posts and you will gain a bunch of info about LS1's and oil issues.

I hate synthetic oil and I will not put it in any of my vehicles. I use Castrol 10w40 in my 99 LS1 car and it doesnt use any oil with 112,000 miles on the clock. And I get on it hard quite a few times inbetween oil changes. The most it ever used was about a half quart and that was when I was going to the track 2 times a week and sprayin the dog **** out of it..
