synthetic oil leaks?

Question

i got a few cars, one with about 98,000 miles (saturn) and a s10 with about 160,000. is ok to use synthetic oil? ive read that using synthetic can ruin gaskets causing leaks.

Answer 1

Synthetic Oils do not cause leaks. Period.

Synthetic oils Expose leaks.

The High detergent action of the oils(IE. higher flash point, lower viscosity) removes sludge build up in the seals from conventional oils. the sludge is a film of oil and dirt and soot from combustion, this slurry works like wet sandpaper to polish metal and wear seals. As long as crank case pressures remain stable ha ha ha no leak , but introduce a high detergent oil and now that sludge is gone allowing the leak to take place

Answer 2

Synthetic oil will not damage gaskets in any way. If you plan to use a synthetic oil in an older vehicle the superior detergent properties clean gum and varnish aggressively. Old hard dried out valve cover, oil pan, main seals and the under-side of intake manifold gaskets may leak in the future.
*Incidentally, Walmart does not sell "junk" oil. You can find Mobil 1, Quaker State, Pennzoil Platinum and others.
Amsoil is great oil but it's sold through dealer networks and the cost is boosted substantially compared to other synthetic oil companies.
If Chrysler and General Motors sell expensive cars (Viper-Corvette) with Mobil 1 in the crankcase you can trust they have faith in the product.
We all appreciate all the oil comparison testing done by Amsoil. In the fine print you will see many of the comparisons are done on semi-synthetics and non synthetics. Apples and apples testing would be more interesting.

No, synthetic does NOT ruin your gaskets or rings.

But it's incredibly expensive. Costs around $5/qt now!!

You might try a synthetic/blend. I used WALMART synthetic- blend for years with excellent results, but they don't have it anymore.

I also used Castrol regular oil in my motorcycle, and noticed that engine ran easier, so their synthetic or synth-blend would be good.

There's now also "high mileage" oil on the market, for cars with 100,000 miles or more. Supposed to have stuff to help keep your gaskets and stuff in condition. But it also might just be little heavier oil so the oil won't leak as easily.

But synthetic works great. Just make sure you don't have an oil leak!! Those drops of synthetic oil can cost you dearly falling onto the pavement!!

Answer 4

you would be wonderful to alter.And have self belief me it won't reason your automobile to have a leak,oil has never brought about a automobile to leak.the way an oil leak starts is at a gasket,or seal has grew to grow to be worn through intense mileage and intense warmth and usually will supply up on the weakest factor. i'm hoping this archives helps ya.

Answer 5

Pure myth about synthetics causing leaks. If you decide to use a synthetic, get a REAL 100%. Not the junk they have at WalMart.

Answer 6

if your car was first designed to use regular oil its ok to use synthetic. If your car was designed first with synthetic only use synthetic. seal designs are different on a synthetic engine

Answer 7

SYNTHETIC OIL WILL WORK JUST FINE, REMEMBER TO BUY A GOOD QUALITY BRAND LIKE MOBIL 1.

you can change to synthetic without problem, but do not go back to petroleum base oils, this is when you get into problems
