Yes, any type F is good, just hard to get here. limited supply or what ever, then if you happen upon a case of it they want anywhere from 6-10 dollars a qt. So why not use B&M? 4.97 from Summit! That oil and that company go back along ways. So I wonder how B&M got the red out and put the blue dye in? Every company has there own formulas for their oils. And if it is just a dye job (which I seriously doubt) so be it, it is still a high quality oil! The stuff works and it is cheaper than I can buy from the local parts houses.
