    5-30wt. mobil 1 . synthetic . walmart I have seen $26.00 5 QT container.

    using 5-30wt in winter and this is the recommended oil, the starts in below 20 deg f are very good.. you can see a slight difference with the 10 -30 wt oil on cranking at temps around 10 deg f...

    where you live using the 10-30wt would be of no help with higher temps ..

    are there trucks down your way with oil coolers aftermarket installed ?

    yes oil coolers are mostly an aftermarket accessory or added in with a towing package (not always), sometimes they are included on the more luxurious truck models im simply speaking about base model trucks which are the vehicles i consider (who needs a lincoln/cadillac truck anyways) and i too am using a 5w30 at the moment from what i read the lower weight actually is slightly less wear at startup from what i've read the first 30 seconds of a vehicles start is the point that most wear is done so i chose to go with the 5w30 and i think i saw that reccomended in the owners manual somewhere too.


    thanks for all the insight

    with the texas heat I was just wondering if most in your area do add this feature. oil coolers up here you do not need as the heat is not very long lived. with months of 90 plus heat and using the truck for work would be a good modification.

    the more you load up the engine , you do heat the oil more.
