What are ya'll doing for oil changes?

Boy I give you credit Grumpy. Why explain it to them. They have already made the decision that this works for them. Right or wrong doesn't matter.

Ya know, every once in awhile I think out loud in print.......

A friend of mine has a '19, he changes his oil every 5,000 km. I know that's incredibly unrealistic and expensive, but to his credit, he has owned some of the worst and best made cars and they all made it 200,000+ km doing what does.

After a sting of Honda Civics which all cleared 350,000 km with ease on 12,000 kilometer oil/filter changes I've dialed it back a bit. Current truck has 205,000 km on the clock at 8,000 km changes and running like a Swiss Watch. 

 

Sad news today. A gal I sold my second Honda to totaled her Saturday at 400,000 km. A car we had bough new and one of the 12 K oil changes.

I don't know what to tell you on this one... I can see how this mentality would have worked 20 years ago... But today, with the improved fully synthetic oils available, it seems like wasted dollars. I think that oil changes are just one of several things that we can do to keep the tires rolling for a very long time.
I'll keep my proven OCI of 5-6K Miles (8-9.5 KM).... And pocket the rest of the $$$.

You don't sound like your old enough to remember when laundry detergents contained TSP. ( Tri-sodium phosphate) Tide was one of the first to dump it as the major cleaning agent and called it "NEW and IMPROVED". Problem was it was indeed new but improved....it was not. Marketing....pure marketing. 

 

The API has refused to 'define' synthetic. It takes no stand whatsoever. Currently a highly refined Group II crude is called a 'synthetic'. If you keep up on the SAE requirements you would see that the amounts of additives is being reduced. Things like Zinc and Phosphorus. Calcium. Ya know, things that make it work. Same story as Tide now being replayed. 

 

What has advanced comes in the true field of synthetics. POE, POA....but alas.....greed is gutting that as well. Mobil 1, once a PAO is now a Group III. 

 

Give the Mobil 1 Annual Protection a good hard look. One of the lowest add packages in the business.

AMSOIL does not endorse reusing their filter.  Just wanted to let everyone know. 

I should hope not!  Damn penny pinchers out there need to man up and get a new filter.

Every once in awhile I run across a guy who thinks a quart in 5,000 is 'normal'. Some accept even less mileage per quart. GM is now handing out nothing in help until it gets worse than a quart in 2,000 miles. I don't share this idea nor accept it as normal.

 

It's not just GM, it's a good number of auto manufacturers out there, including companies like Crapota and Honda.  The culprit?  Low tension piston rings found in many if not all modern engines now. 
The issue with low tension piston rings is that they have a greater tendency to allow blow-by. Crankcase contamination compromises lubrication and of course results in oil degradation. ... Or, vice versa, stuck rings can promote oil consumption and intake deposit formation due to engine oil moving up into the cylinder and into the intake.  Which is why running good additives in today's modern engines is critical.  To help clean and keep things smooth.  Believe it if you want, I do.

What kind of additives are you using? Curious and would like to look at it. I’m not so good with the truck stuff [emoji23]. Learning though, haha. I just changed my own oil for the first time...ever. [emoji1750]This thread basically pushed me to do it. Lots of good, sometimes conflicting, information.

The other main issue is our quality of fuel.  If we had a cleaner burning fuel it would benefit big time.  The issues on diesel over in Europe don't have to deal with things like we do here because their fuel is a much higher quality fuel.  At least that is my understanding.   Also looking at vehicles that run E85. The combustion chambers are clean with little to no deposits.  Big oil can produce a higher quality fuel but that would cut into their profits way to much.  Better to push crap on us and make the big bucks.

Preaching to the Choir. Fighting this battle right now with the 2.4 in my wife's Terrain. Gum and varnish.

 

Combustion pressures hold the compression rings to the walls, not ring tension. It just makes the introduction. That said gum and varnish will hold a low tension set collapsed (GM's term) where a standard or high tension ring would resist. Their solution is to re-ring on new pistions 100 K mile motors without a hone. Showing they know the ring isn't worn out and the wall is not glazed. Just gummed deep into the land. In any event it is indeed the low tension rings at issue. Agreed!!

 

So how is it this happens using a Dexos approved oil changed more frequently that even GM suggest? OCI is still to long even at 5 K for that paticular oil. QSUD and 5 K was the standard I used from day one. Thus a 3 K OCI is in order or an oil less prone to varnish. Even a GM memo has made such a suggestion. (posted in another thread)

 

This particular motor doesn't have a PCV valve but rather an orifice system. This system allows oil ingress to the manifold when a normal PCV system would halt such flow. There was a bright idea, eh? 

 

Passive or active the EGR has been a non event mandated part of emissions since 1973.
