starting a new thread from the one i posted to get everyones opinion on oil.
04 4.0 132,400 miles chicago stop and go traffic and a some weekend highway runs. want maybe a synthetic for winter so i dont have to get out in snow and change it. right now i have 10w30 max life syn blend. so here what my options
mobil 1 hm 5w30 or 5w40 rotella t6 5w40 or the max life blend 5w30
it gets hot in the summer and really cold in the winter like windshield of -10 and iam sticking with mobil 1 filter
I have run conventional Valvoline 10W-30 and have for probably 40+ years... never a single engine failure. Today's conventional motor oils like from Valvoline, Mobil, Shell, Castrol, Pennzoil etc. are superb and I'd run any of them and know my engines are all being extremely well protected.
And contrary to what some marketing departments would like us to believe, a synthetic motor oil is not needed to protect our engines. Only if I lived in an uber-cold area like North Dakota, Alaska, Buffalo NY, etc. would I pay extra for a synthetic motor oil during the winter which has been shown to be worth the extra $$$ in those extra-cold conditions.
