2003 Super Cab XLT Engine Oil

The manual calls for 5w-30 recommended year round. should I do other wise? I usually put the thinner stuff in the winter and the thicker stuff in the summer.

if you are a 4.0L, just run 5w30. If you want thinner stuff for winter, find a 0w30 for thinner cold cranking viscosity.

I should actually say in the manual it says "Do not use supplemental oil additives, oil treatment or engine additives". Now does that imply to only use conventional motor oil aka straight oil?? I personally do not see any need to use anything else because this it not a high performance motor (although it does haul ***)

I think by additives, they are talking about Marvel Mystery Oil or Lubro Moly. Gas has additives. Conventional oil has additives. You can surely use conventional oil if you'd like, but you will have shorter oil change intervals.

No Slick 50 or other crap like it. FWIW, I don't even use that crap in my race bike, which operates in the 13,000+ rpm range all the time.

Absolutely no sense in the store-bought additives anyway considering most decent oils mfg's already have the proper additive package necessary.

I'm not going to debate oil but I will say that synthetic has its place and it isn't anywhere other than severe duty situations, IMO.

I run MaxLife, which is a high mileage synthetic blend where I get it. I don't trust the previous owner on how reliable her oil changes were, so better safe than sorry. Maxlife has a higher ZDDP additive which is supposed to protect a bit more for wear.

Wife's car gets synthetic. She puts on 2k miles a month and I don't want to change oil as often.
