Exactly...

 

Nobody asked you! :P

As a moderator, are you not supposed to identify and delete trolling posts like that?

 

May I have your permission to hijack this thead, William?

I'm wondering about oil. I'm heavily considering switching to synthetic oil, because it looks like I've got my oil leak situation sorted out nicely. Is it worth the money to switch to a synthetic on an engine that already has 225kish miles on it? I'm thinking about using Rotella T6 synthetic. Is that a good synthetic, or would I be better served with something like Amsoil or Royal Purple? I'm considering using T6 for the initial swap to synthetic, to see if I like synthetic and to flush out all of the dino stuff that will be still hanging out in the engine and high pressure oil system. Then, if I like the synthetic, I would switch to a more hardcore synthetic, like Amsoil, Royal Purple, or Schaeffer's.

Does that sound like a good plan or am I just over-thinking it?

 

Here's my $.02.
I've run just about all the oils at some point.
And from what I see working on these injectors everyday, and talking with hundreds of truck owners a year as to what works and so forth.
I say run the cheapest oil you can find and change it out at 2500 miles, 3k tops. A supply of good, clean oil will not only help the injectors, turbo, and HPOP, but the motor as well. 400k miles plus, and a few over 500k miles I have personally witnessed, all change oil at 2500 miles. Usually fleet trucks maintained with bulk 55 gal drum oil, which is nothing fantastic by any means.

I ran Amsoil for a year. MAN is that expensive. $200 oil changes, PLUS $150 bypass filter, PLUS $30 oil analysis to see if you can keep running it? Not for me.

I ran Valvoline Premium Blue synthatic. I might do that again, as I can find it local and it's not horribly expensive, but change no more than 6k miles.

If you plan to keep the truck forever, I'd say run synthetic, or just make sure to change the oil at 2500 miles.

 

Good info Jim.
And i agree. I hate hearing how people with the big donaldson filter and synthetic oil do a swap like every 10k miles... AH!
I run the big donaldson and run the schaeffers premium 9000 synthetic and I do 5k miles...
It makes it easy cuz I can do a tire rotation and check the brakes at the same time.
I like schaeffers because ive had good oil anylsis come back from it (the three times i did it) and the price is comparable to royal purple (depending on which vendor is near you) Some of them really jack it up.. ive got a good one near me.
But also on Bobistheoilguy forums Ive read many-a-threads about the less oil consumption and boil over with schaeffers when guys are hauling cross country.
But hey thats my pennies in the pot.
