Oil ...... Is going to 0-40W synthetic smart?

[Frostbite]

I just got my new injectors today. I plan to install them this coming weekend. As part of the injector change, I will be doing an oil change afterward to make sure that any fuel that runs into the oil pan doesn't get cycled back through the motor.

I have run Chevron Delo 400 15-40W since day one in my truck. I have heard of guys running synthetic oils but, I have also heard that maybe they aren't good for the longevity of the motor. One guy at work mentioned Schafer 0-40W synthetic. That sounds awfully thin to me. I see there is Amsoil 5-40W and their stuff certainly is reputable. I know this question is like asking what is the best kind of beer but, is now a good time to swap over to synthetic oil?

Is the Shafer even rated for use in a compression engine? Cheers!

I have no idea. I am compelled to stay with Delo 400 because it has worked well for me but, I am open to listening to what you guys have to say.

i use rotella 5w40 synthetic in the truck. but i use 0w30 in my sled with no issues if that helps

X2 on the rotella T6. No issues, starts better and a little quieter especially in the winter.

You can swap back and forth between synthetics and conventional at any time. What is Schafer 0w-40? Do you mean Schaefer's? Check to see if the oil meets any of the following specs CI-4, CI-4+ and/or CJ-4? If it does run it without worry, if it doesn't have a C-rated classification on the API donut don't put it in your truck.

Honestly, this time of the year is it going to be worth it to put a 0w-40 in your truck...will it get that cold? I mean a 0w-40 weight oil is designed for use in the arctic circle.

Stick with Delo, if you have no issues then keep using what you got in there.

I *always* go with synthetics, in EVERYTHING.

[ZMANN]

if u like Delo go with this Delo 400 LE Synthetic SAE 5W-40 (API CJ-4)

but Getting the Dino oil out of the system for e was key since stiction is an issue for Me

But not really for you,,

I run Rotella t6 myself I did see some schaeffers oil is diesel rated but I didn't see the cj-4 endorsement nor could I find a 0 -40 or any 0 viscosity oil on there site??Then again I didn't look at it very long lol

Ive heard if you put synthetic in your vehicle to not go back to normal oil. Keep that in mind
