It is interesting to note that other synthetics produced considerably more deposit than the petroleum. Petroleum evaporates more readily than the synthetics, so more of the synthetic remains to thermally decompose into a hard deposit. The thermal stability of the synthetic hydrocarbon used in other synthetics is only slightly greater than a petroleum hydrocarbon molecule; however, the polyol esters in Red Line are capable of at least an additional 100°F before breakdown.
The above was from the Redline site
At the Redline site is a graph showing how some oils performed . The wts are noted with a letter designation for the brand which at least to me is easily indentifiable as Amsoil , Quaker State , Kendall and Mobil .
That said , the Kendall 20/50 dino actually left less hard deposits than the Amsoil 20/50 synthetic and the Mobil 15/50 was the clear leader of the pack " under Redline that is " in resistance to form hard deposits which raises a thought about Mobil's Supersyn Formulation . Since the 15/50 is so near the same formulation as the 30wts in the Mobil line up.... would it be possible that the SS 30wts are the clear leader of the other synlubes when tested in the same VI in terms of engine protection against these hard deposits and overall engine cleanliness over the course of an engines life ?
Apparently Amsoil is dumbing down the additive packs of their 30wts based on new analysis here in the last weeks while Mobil seems to continually tweek and upgrade their SS oils that now contain relatively huge additive packs in comparison .
Also , it's interesting to find that some formulated Pao's can actually leave more hard deposits than dino's , per Redline .
