Well, I'm afraid I'm with Jay on this one. Synthetics are as far as I’m concerned a waste of money for the most part. There is no significant documented proof that they’re any better than conventional mineral oils. Yes, in extreme temperature conditions, I could see a synthetic brand having an advantage over a dino oil, but otherwise, there is no justification for dropping $50.00 on an oil change on a daily driver, when you could have just as easily done it for less than half that price and achieved the same over all result. Improve horsepower, fuel economy, compression, etc, etc….give me a break. I’ll take the $2,000.00 I saved over the life of my vehicle that you guys spend on buying synthetic oil and spend it on something that will really improve performance, or put it towards the cost of a rebuild. The only ones, who make these outlandish claims, are the manufactures of the oil product themselves. I have yet to see any real world controlled testing that proves this “theory”. If dino oil is so inferior….how do you explain all of the 250-300+K engines out there, that have run on nothing but, they’re whole lives? As for the comment about synthetic oil not drying seals and gaskets…..try the exact opposite. Additives in synthetic oil break down the rubber and silicone properties every bit as much as conventional oils do, which over time causes them to turn to stone. Due to their lighter (thinner) properties they’re more prone to leak like a sieve…especially in older vehicles.
Nope, for my money it’s a decent brand name conventional oil, a good filter and regular oil changes.
