Oil Type?, what type is best Options

[Praying_Mantis]

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

its a myth thats been passed down from person to person for soo long that its hard to break the cycle.

its just about IMPOSSIBLE to find reliable and truthful information about oil on the internet due to extreme amounts of advertising put into pages and reviews by mobil and amsoil and other companies.

if i could find a true unbiased non advertising article i would link it, but ive heard from many people that are REALLY in the know (dealer techs with 30+ years working in the automotive feild and ASE certified master techs) that switching to synthetic doesnt increase your chances of an oil leak anymore than the reason the sky is blue is because of all the water

an old engine will leak oil no matter what you do, it just happens and its such a hard thing to scientifically study. just because mr x has an oil burning issue at 180k miles and he switched to synthetic and now it blows blue smoke doesnt mean its because of the oil, it could be countless other things. hell it could be because the synthetic cleaned away the varnish and sludge that was holding the engine together :lol:
