Oil Filter Thread

Well, @ least change every 5k miles and you should be ok, minimal deposits restricting oil flow through all their little orifices (VVT, MDS, Piston Cooling Nozzles, etc.)

So yes the esp and that ilk is a great oil but made for euro diesels, still great in a hemi or di in some cases, but with a ten year warranty and an engine that needs to be clean to operate correctly meaning you have a greater chance of needing a warranty on that, I would follow dealer recommendations.

Yeh, I didn't know or consider that the new Hurricane 3.0 liter turbo engine was GDI ... ?

I looked up the engines specs and set up and it is a GDI fuel delivery system.

So, yeh that is a filthy fuel delivery system that will eventually have carbon build up on the backside of the valves, etc. and burning top tier fuel ain't gonna keep that from happening because of how the fuel is delivered vs the recent old reliable Eagle HEMI v-8 engine.

The 'rubber band' powered 2025 truck I currently have is a GDI 3.8 liter v-6 and IMHO, keeping the oci's @around 4500 miles max probably be more beneficial. I'm not using what the manufacturer/owners manual states(0w/20, my truck specs 5w/30 outside the continital US because of the bean counters/tree huggers/EPA ).

I'm using and oil(Valvoline Restore and Protect 5w/30)that is formulated for GDI type engines ...

There's two turbos on that thing - that's how they get more torque out of only 3.0 liter displacement. But like anything, higher power out of the same space usually means accelerated wear and shorter life. I am positive they are counting on that motor not seeing many high load events.

For GDI we need a breather coalescer. That is the proper term, not "catch can". We never called it that in industry, never even heard of it. Top Tier fuel is still important for the injector nozzles, because a GDI injector lives in a much dirtier and hotter environment (cylinder) than a port injector (intake manifold). Despite the much higher pressure of injection. All that incomplete combustion (soot) during rich burn mode deposits on the injector tip sticking into the cylinder. It's a terrible architecture for only 5% better fuel mileage (+20% was promised by Mitsubishi in the 90's).

Oh, and also an occasional chemical scrub. That cleans the intake valve. I've been using CRC intake valve and injector cleaner. Then change oil right afterward. Instructions are on the can. For the 2 Mazda CX-5's we have, but applies to any GDI motor.

Absolutely, that's what I was a be try'n to say.

He has the HO that calls for 0w40, so you at least know why I thought 3k miles. These things are up to like 90k out the door for a 1500, I'm thinking a little extra maintenance keeping it clean with heavy shearing vii oils.

It's just crazy - throwing all this $hit at vehicles to eek out a few more tenths of a gallon of fuel economy.

I only run Shell 93 octane and I do have a catch can installed.
How does a "chemical scrub" clean the intake valves on a GDI motor?

You spray it into the air intake with the engine running, downstream of the MAP sensor but before the turbo compressor. So it cleans the dirty compressor blades too. The PCV return line port into the intake is the ideal port to use.

So, it acts like the port fuel injector does.

$82 for an oil filter?!

PSST. It's a 6-pack.

Looooong day in hot sun today.

That's what I'm going with, anyway.
That one looks like the RP 20-820 & Fram XG2.
I can't use that one for my HD 6.4, too large.
I'll look again when I get time, but PGI website didnt have a spec page.

You can find them at rockauto for reasonable prices. I just linked the first path i saw.
