I stand by my claim that 99% of the current market of engines don't require synthetic oils. "True synthetic" was what this post was about, I didn't call it a true synthetic or not merely replying to a question as to why some people are asking what a true synthetic is. I don't see why when someone ask a question about a synthetic it comes up as the oil makers business as to what someone needs ? If it's a huge burden for you about what is a true synthetic verses the group III then try to educate as many as you can, however if it makes you really upset when someone says true synthetic I think you will battle a lost cause. I myself don't care what it's called, and I doubt I have ever used a "real synthetic" so your preaching to the wrong one doodfood. With the 5w-20 I don't think 5w-20's need to be deemed synthetic just because they are 5w-20, I do think that oil standards have now come to be in present times because of the vast use of 5w-20. Also synthetic is pushed on this site as being needed to keep your engine clean, for the extra protection it offers, and for longer drain intervals, and some way as being cheaper by extending drain intervals. I find that none of these are true, and the offering extra protection is a real burden for me so I try to educate people as finding out how they can use the extra protection before jumping on the bandwagon. I use synthetic myself in a engine not required to... so don't think I'm a conventional freak I just see so many times things being posted with the whole synthetic verses conventional, then I see your point to you add the synthetic verses real synthetic information just gets lost in the abyss.
