new car uses it. finally found some at walmart in 5qt jugs. heard it was out there but have never seen it. only $23. was buying qt bottle before at $6.35 each. so i save a little. wish i could use 5w-20 since its easy to find. gotta use what the factory says since we have a warranty. i see they have bio-degradable syn oil now. in black bottles. never seen that before.
