4 gallons of oil and a fleetguard filter

KKB

If you are using 4 gallons and a filter you are using 1 gallon too much. They only take 12 quarts including filter which is 3 gallons.

Wrong! My truck uses 13 quarts!

DodgemnLeavem

so does mine But I dont buy the 4th gallon just one more quart. I never need to add any so I dont see the point to get another Unless its on sale.

silverrhino

I was referring to the person above me only saying he needs 12.

Honestly, I don't buy my oil in one gallon jugs. I order it in 55gal drums (DELO 400), of course that is for shop use.

tcr

Why 13, do you have an extra external filter?

justin mcfall

X2^^It says to use 12Qts.,or am i wrong..

surfram

Pour 3 gallons(12 quarts!) in, don't worry about it anymore. That is what the 5.9 is supposed to hold. If you are doing the add-a-little and check the dipstick game, you are wasting time...

KKB

Exactly what I was getting at above. It says 12 quarts which includes the filter. No where does is say 13 quarts for my truck.

checkster

12 quarts here, every oil change.

DodgemnLeavem

well MY TRUCK says 13 quarts and thats exactly how much it takes WITH filter, if I dont put in the last Quart(13) it shows 1 quart LOW every oil change.

not everyone has the exact same thing. see just cuz one guy does it dont mean its right for you.

checkster

hey man imjust tellin ya what i do, im not preaching do whatever you want.

silverrhino

Mine takes 13, That's just how it is. Just like dodgemnleavem said, not all trucks are made the same (along the same lines of why some peoples stock tranny lasts longer than others). 12 quarts will barely touch the dipstick. So I add the extra qt. Kinda seems stupid to skimp out on the extra quart, especially since engine oil is probably one of the most important things to keep these motors running!!

mine takes 13 to fill. that is why i buy 4 gallons

DodgemnLeavem

no need for that^^ Im just telling ya what I do. Too!!
