I run German Castrol 0w-30 which actually is more of a 10w then 0w, however it has excellent wear characteritics and has a hard time breaking down over time. I'm my LS1 I run either that or Royal Purple 10w-40. The reason I ask, is because the 4.0 SOHC are made in Germany and well, why not use german oil in them. Just asking what y'all use.

5w-30 mobil

 

5w-30 Motorcraft

 

10w-30 full synthetic valvoline

 

5w-30 Amsoil Sythetics with Amsoil Filter

 

I used 3 flavors of M1 syn with 45000 miles of m1 5w40 syn being the most used. However now that I aquired 20qts of pennzoil platinum for 2$ a quart that is next up to be used... and after that is the 25qts of valvoline max life syn that
I got for free... It seems they had this promotion where you got
the oil free to try out after rebate (had to pay tax)... Well
lets just say my grandma, dad, girlfriend, and other grandma
all decided to try it out too :) (it was limit 5qts per address)

was using mobil 1 but just ordered amsoil 5w20 so that is gonna be put in there.

 

5w30 castrol GTX (only when its winter) And I just switched to 10w30 valvoline to try it out. (and i switched to 10w30 for the summer so i dont burn as much oil. little thicker)

Castrol Full Synthetic 5w-30. Got the truck with 2871 miles, changed to Castrol Blend 5w-30 at 3K, been running full-syn from 8k on at 4-6K changes. Currently at 32100. Filters have been Fram tough guard, but the last 4 changes have been Pure1 Purolators (PL24651 is the # I believe).

 

In My truck and Expedtion Valvoline, 5w20 with a Wix Filter.

In My Cadillac, Valvoline Maxx life (75,000 mile and over oil) with a Wix filter, changed once a year, as I hardly do more than 2500 miles in a year.

The Charger is Filled to the top of the oil filler, with the cheapest generic oil I can find. (Motor Doesn't run and needs to be rebuilt, just wanted to keep it from seizing)

The explorer gets what ever they sell at Carquest, It has 182000 miles and I plow with it, It's got bigger problems than what quality of oil I put in it.

Just to let you know, Fram filters suck ***. You want to use a WIX type filter: Napa, STP, Penzoil, Purolator. Mobil 1, Bosch, K&N, Amsoil are other types, but a hell-ov-alot better than Fram. The reason being, is that the Frams filter media breaks down fast, even by 3k miles. The other filters down break down as fast and have even more filter media to catch more and some filter better; smaller particals caught.
I'm just trying to spread the knowledge so that your engines and trucks will last longer and just be better overall.
