Amsoil 10-30 full synthetic. Royal purple is the worst oil u culd put in ur car. Id rather put water to be honest.
castrol high mileage. and a wix oil filter. now that my wife works at a toyota dealership im going to be using the toyota filters. better for starts i was told.
rotella 15w40 and a fram filter in my big rig its highest zink of all oils and its geat for new or rebuilt engine break ins ,,,
I never used Royal purple nor shall I ever. Glad you guys are using synthetic though, that stuff lasts longer in HOT and COLD, we're talking about the oil itself in either conditions.
it says on my oil cap, 10W-30, and my owners manual. 10W is on the cold weight, the second is the warm/ hot weight. I'm not sure if there was a difference in the cold, but i used 5W-30 for a winter, went back to 10W-30 and stayed that way. my OCI's are only 5k right now and I feel that i'm short living the filters I use. The Toyota D1 size filters for our trucks have 160sq.in. of material. My PL30001 has 400sq.in.... I might use my filter for every two OCI's?
