I may have reposted here. To my untrained eye, it looks like it's performing better in the vehicle than the spec. sheets would indicate. I do use SuperTech dino and have had no troubles with it, although I haven't had it tested.
quote:csandste, Don't take this the wrong way. How do you know the SuperTech dino is so good? This is coming from someone who just learned the value of analyzing recently. Just because I don't hear bad things at startup or during acceleration doesn't mean excessive wear isn't occuring. My unscientific look into the valve cover was probably useless too. Near clear oil when draining? Maybe the oil is failing to suspend contaminants and is letting them form deposits. When I did my first analysis, Terry Dyson alerted me to a head gasket leak. Maybe I'm a worrier, but I can't say an oil is good until I analyze it.

quote:I'm just saying IT'S MARKETED AS A FULL SYNTHETIC 5W-30. I'm not talking about the dino 5W-30, or the "full synthetic" 10W-30 SUpertech which people are assuming (the person that posted a link to an oil analysis of Super-Tech synth 10W-30) They are different because the 10w-30 is only API SJ/GF2 the 5W-30 is SL/GF-3. Must be using different additives o rosmething, either that or Super-Tech has a newer 10W-30 formulation that hasn't hit the shelves yet. Regardless its one of the least expensive Group IIIs around at $3/qt if its a Group III. So far I've been hearing that both QS and Pennzoil use PAO base stocks with Group III additives, and then there are ppl that say QS and Pennzoil use Group III base stocks w/o showing any evidence to substantiate that claim. QS's MSDS shows that it has a PAO base stock, however that might have been the older formulation since the QS Synth with the PAO base stock (1-decene ....) is only GF-2, while the QS Synth on the shelves are GF-3.
