Rotella "synthetic' Isnt really synthetic at all... Its group III petrolleum.
That said, the price is right, and Id use it in lawnmowers and stuff that wont necessarily benefit from mobil1 type synthetics, but could use a little wear reduction or need to stop burning so much oil.

All I can say is at least shell charges a reduced price for their fake synth, unlike castrol who charges M1 prices for their group III fake synthetic!
