Whoever told you that is full of shit. Synthetic oil lasts longer, doesn't burn as fast, and it is more viscous than regular oil. You'll only be hurting your engine if you put synthetic oil in a brand new car.

Doesn't hurt to put WAY better oil in your 2002 GTS, just don't make it 10wieght untill you've reached 50K miles. thumbsup

synthetic oil is the same viscosity as conventional oil of the same weight... it just doesnt lose its viscosity as quickly.

Actually, synthetics are better when you start using them in newer engines. it's the way the seals kinda atune to it. i've seen cars that put in synthetic after using reg. oil for a very long time and end up blowing their seals. generally i say you need to start using it before 15k miles and don't switch back and forth, once you start using synthetic, stay with it cause it's bad for the engine to switch between the 2

Im not saying your wrong, but why would switching between the two be bad for it.

well, in the past, regular oil did not have additives that current synthetics have today. this caused seals to crack ever slightly. what prevented leaks was the oil "sludge" of older oils. it had a tendency to accumulate within these cracks which is why no leaks were seen. now add synthetic to that which is made of of smaller particles which are able to pass through these cracks easier which caused leaks.

now most modern synthetic oils have additives that keep the seals flexible and less prone to cracking. which is why i said you should start early with synthetics. keep them seals in good condition.

most regular oils now have the same additives, to help with seals.

but most regular oils can leave that burnoff "sludgelike" deposites in the engine still. synthetics are not nearly as bad about it.

mostly it's my opinion that if you start using synthetics to stay with it and not put regular oils in unless it's an emergency.
