This is so funny. I started this thread thinking I'd go with either castrol,mobile 1 or motorcraft. I can get all 3 here but the dealer sells motorcraft for 13 bucks a quart! I can get mobil-1 or castrol for 8.30 a quart...I use redline oil in my truck all the time. I also use redline for my truck manual transmission and differential oil... I was originally gonna use redline for the boss.. but saw that most ppl were using motorcraft or castrol for warranty issues... I f I can use it for the boss. that would be awesome. Love the product.
