Greetings!
Iv'e been reading quite a bit of past posts here and find this website very informative. I'm a huge Mopar nut, and found a few things you guys have mentioned to give me pause to ask a question or 2 of you. I've used Valvoline conventional oil in everything I have owned with good results. I change oil/filter every 3K on all my vehicles. My Jeep Wrangler 4.0(97K) gets 10W30, my Chrysler New Yorker 3.5(128K) gets 10W30 and my wifes Voyager 3.0 gets 10W40(150K)and my 1958 Plymouth Savoy gets 10W40(160K).I see many of you prefer Havoline, and many of you posted comments saying I should probably go with a 40 weight in the Jeep. No smoking/leaking problems on any of the vehicles except the 58 (Oil seals/engine rebuild needed...I hardly take it out so it's not an issue)
#1) Would synthetics or heavier weights do me any good on any of these vehicles, in your opinion? Weather here is temperate, with a few days a year in the low single digits but most winters avg 30 Deg, summers 85 Deg.
#2) Have I been misled all these years on Valvoline's quality? Any comments you guys can give me would be much appreciated, as I plan on taking your advice
