SynLube is an extremely small company that does not have any advertising except for its webpage. Even to many who have been in the automotive industry for a long time, their existance is still a surprise and they obviously cannot compete with the more powerful competitors here and don't even try.
Despite Callisa's blanket refusal to consider SynLube's advantages, I believe the information that I provided you is essentially correct. I am not an oil expert as Callista claims to be (and may well be) but I have seen "experts" deny the quality of this product many times before. The two most frequently given excuses for writing SynLube off are: 1) If it is as good as is it is supposed to be why aren't car manufacturers using it? 2) If it seems too good to be true, then it probably is. When I hear those responses, it's as sure as the sun rises, they have made up their minds to ignore it whatever the cost.
The BobIsTheOilGuy site was particularly resistant to new information treating SynLube from the start as a snake oil. Many of them claim to be experts but true experts learn about something before making a judgment and I didn't get that sense from many of their responses.
One of my theories about this kind of behavior is that oil guys love to talk about how clean their oil is after 5K miles and how the oil analysis they just got back shows that there's no problems. Switch to SynLube and all that enjoyment's gone because you can put it in a properly operating engine and just about forget it except to check for proper fluid levels once in a while. Life gets very dull.
I've seen this happen with bicycles. When I got started with them back in the 70s, the parts were very poor. Shifting was terrible and failures were frequent. There was a sense of excitement with every ride and if I got home without a problem, it was great. With better components came better performance and reliability and cycling became less exciting.
As I've pointed out, I have almost 4 years of experience with this lubricant. I have never had a problem with it. Oil consumption runs about 40-60K miles per quart. My fuel consumption is generally better than others who have comparable vehicles (Focus and Ranger), even those who claim to drive as conservatively as I do.
Being a skeptic is a good starting point for investigation if it doesn't mean rejecting information without justification. Why don't you read through the pages of the website and see if you don't see some one who is writing in good faith. I admit, the style of writing isn't great but Miro Kefurt is a member of SAE and has a thorough background in chemistry that shows in this oil formula. Finally, e-mail him with a couple of questions about things that concern you and get his response. More than anything else, his common sense responses to my questions were what convinced me to try SynLube.
One final point: The latest version of the SynLube formula, introduced in 1996, exceeded the new API SM and the ILSAC GF-4 (?) specs without modification.
