I am 55 and have religiously used Castrol my entire life, stated off with regular Castrol 20/50 conventional in my first truck when I was a kid that was an 84 Toyota pick up with the unbeatable 22R motor. Since I bought my 2011 V-6 Tacoma I’ve always used Castrol Edge 10/30 but I noticed they’ve changed something in their synthetic too something called “Carbon Neutral” so since I don’t know what that is I just switched today to Valvoline Full synthetic 10/30. Just curious what you all are using? Also what filters ya like? I use “WIX”. Hope all is well with everyone and I look forward to hearing from you all.
