Re: Oil ratio for a Scott Atwater 16

[Casey Lynn]

Synthetic oils!
Most are not synthetic at all but are mineral based oils, changed, massaged, and added to that perform to a certain standard and are thereby labeled "Synthetic" by the manufacturer.
SAY WHAT???
Almost all of these "Synthetics" are what are now commonly referred to as Group III oils. Don’t get me wrong, they are good at what they do. But, are they worth in some cases twice the price of a standard dino oil? Do they protect twice as good? Ever read what it takes to submit a warranty claim to Amsoil??
Point here is that if you are using a newer oil that is better for the environment, good on you! If you are using a "synthetic" to drop your oil ratio or oil costs well…not so good. Your failures may not be sudden however accelerated wear will happen. Not so much due to the oil as much as the early design and material make-up of the engine.
