technically, it isnt a good idea to switch to syn after running regular for a long time. the syn has more cleaning agents in it, and will remove alot of built up material around your gaskets and cause your gaskets to leak. switch back to regular, and you will be fine. its best to run synthetic from day one, or while the engine is still very new.

NO! There IS a problem with the engine. The thinner oil is finding a leak, and leaking out. By using a thicker oil, it is not leaking. If you have a really leaky gasket, I guess you just go get some paste and fill her up...

there is. The thicker oil is just hiding the problem. Sence its thicker its not as likley to seep out from where ever its leaking. Its not a big deal, but it can be a sighn of things to come.
If it is leaking oil then how is there no problem? You can cover it up by using mineral oil but that doesn't make it go away. You have damaged seals and/or gaskets that need to be replaced if you want your engine to be clean.spanky442 said:
I switched to synthetic (Mobil 1) on a vehicle with over 200k miles and it was always lubricated by petrol oil. No leaks and the gas mileage improved quite a lot. That tells the engine was still quite healthy.

I switched to full synthetic at 88,000, now I burn about 1 qt. every 1,000, as compared to 1,500 miles with the blended oils. I know I have some small leaks, but it's worth the extra protection in the winter. This year I've had a few starts in the A.M. at 5* outside, and I hear no tapping whatsoever vs. when I used to use the regular or blends. I'd rather spend an extra couple of dollars between oil changes and add and extra quart instead of wrecking my engine. Summer I use Mobil 1 20w-50 and use even less oil. Don't blame the product, blame the car.
well, no matter what we use, they are going to go through some oil. I just don't know if its better to switch or just continue with what car is used to. relax people, the engine is fine, its 11yrs old I'm sure its going to go through some oil and may have leaks. Its not smoking, and oil is not mixing with anything else. Compression is right where is should be so in worst case I may have to do the valve cover gaskets or pan gasket one day.

yeah with mobile 1 I started at about 109k and right now i'm at 115k and leak a little bit of oil out of the pan, well maybe alot but since I'm redo alot of the engine I'll just stick another gasket in there and I should be good to go.

If you used 5-20 dino oil, I am sure it would lose oil also. I think its a matter of the viscosity, more than the type of oil. If its the org engine, the normal wear on parts ans seals will not like the thinner oil.
