All the big oil companies got a line that just sticks out to me as something unique. In BP/Castrol I think Magnatec 0w20 is the business. Valvoline had it with the VML red bottle especially 5w30. Great high mileage semi-syn oil.Pennzoil Ultra Platinum pre-GTL was awesome in 5w30 with a Noack about as low as they come but later poor distribution made this oil lose fan base. M1 get my node in the 0w30 & 0w40 weights only.Great at 5.99qt at Napa. Redline oil 0w20 is stout and runs well in little sewing machine engines like mine. Love this oil, dont use if you consume a lot of oil or cant part with 11.00 a qt. Definitely overkill. Not a fan of their OE line;stick to the Race/Street line only. Royal Purple was great in 2000's as a Synerlec oil. Bought it religiously at Napa in 5w30. Wish they would lose the SN line completely as its fair at best but the purple dye was great for reading dipstick after oil change.Amsoil has a following. Liked the 2000 series in 0w30 when its all they made and push for true syn oil. Having brochures is a plus as some dont care for the new way of Internet research. Trop Arctic was a great 1.99qt synblend that was sold at Orschlens while back. Great product in 5w20.
