i haven't changed my oil since i bought my car a while ago so i think i'd better give it a service. Just wondering what the best type to use is ie. synthetic, semi synthetic or a good quality non synthetic? cheers

Fortunately, oil manufacturers learned their lesson and reformulated their oil to contain the proper additive package which helps condition seals and gaskets to maintain their flexibility while also maintaining proper seal swell. In fact, the reformulation in most cases provides for better seal conditioning than most petroleum oils these days. Nevertheless, there is still a possibility of leakage if making the switch to synthetic - but only under certain conditions. Please allow me to elaborate a little bit.
Any of you who are considering a switch to synthetic oils probably know by now that petroleum oils do not necessarily keep your engine squeaky clean. Well, if you own an older vehicle (over 8-10 years old) it's possible that you have leaks in your engine already. Now, before you string me up by my toe nails telling me there's never been a drop of oil that leaked from your engine, let me explain myself. On older vehicles which have been lubricated with petroleum oils, seals and gaskets can begin to dry and crack. The reason you don't actually see leaks is because petroleum oils tend to burn off and leave sludge, grime and varnish on the inside of your engine. That's simply the nature of a petroleum oil's make-up. Now, conventional petroleum oils are not very discriminatory about where they leave those deposits. Therefore, some of the deposits end up around your seals and gaskets which actually plugs up the gaps which would have resulted in oil leaks. Not even close. The fact is, it's a result of using petroleum oil instead of a high quality synthetic that resulted in dry and cracking seals & gaskets in the first place. As I mentioned earlier, synthetic oils now contain special additives which maintain proper seal swell and keep them flexible so that seals and gaskets don't dry and crack in the first place. So, for those people who use synthetic oils from the start (after a 3,000 to 5,000 mile break-in period), the problem never becomes an issue. so i guess you didn't read that part of the propaganda realy close? it says you engine is leaking but you just dont see it. and i still dispute the validity of this article since it was written FOR Amsoil by someone who sells Amsoil. -------------------- |
