Synthetic Oil

My biggest worry when I went to the 6.2 pil pump was excessive pressure. Wanted the volume at similar pressures so happy with it

I bet those lifters pump up real quick....LoL

Sure is lovely!

Idk what my truck does with TBN never had a UOA. Was going to after the hpl supercar change but i drained the oil into a dirty pan and then dropped the sample on the ground lol

Where abouts in michigan are you from? I see your profile says from michigan

Jackson Co. love my property but absolutely hate this location. 21 acres and only 1.25 of it is yard. Rest is wetlands and woods

Is this in a 5.7?

Yes, I spoke with HPL and they advised this oil. Truck has a high lift cam, and a 6.2 oil pump, with non MDS lifters

Don’t forget the minor detail of adding extra oil of you go to the bigger filter.

Yep.
At my last OCI, 12/2023, I gave my mechanic 8 quarts of PUP 5W-20 and a RP 20-820 filter. He added 7.5 quarts and gave me the 1/2 bottle left over.

This dipstick is sitting right at the FULL mark.

Aye!

If Si-1 can clean a combustion chamber nice and slow as we see, why can't we use it in the oil straight away as an engine flush? I mean dudes put oil in gas and call it an additive, why not visa versa? It ends up there anyway?

and... why did it take 15 years for someone to ask that one?

SAE PEA wont cause sludge and is the most effective product for cleaning carbon.

If it can clean a combustion chamber it can clean an engine?

propylene oxide-based PEA is an issue, is that is what is used in fuel treatments?

I mean now there are many types of PEA, my brain hurts.

Sounds good but imma need to see a project farm video to know for sure.

Don't need in oil.

Need in fuel flow route. The carbon that plates is in the fuel, not the oil.

Btw, I read Ford has added a 2nd injector to at least some of their ecoboost engines, joining Toyota.

About damned time. Buddy just picked up a new Ford F150 with 3.5L Ecoboost. Some reporting they can make it to 150k miles as grocery getters, unlike the 70k or so miles when they 1st came out.
IDK how you can PFI gasoline into a boosted intake manifold. All new to me.

I thought PEA really dose its best work during combustion?

Well HOWS the posi-Trac on the rear end of a Plymouth work!!???

It JUST dose….

Extra port induction usually works at idle or very low/no boost times, therefore, not being blown around with high boost.

It's been around a while. All GDI engines should have had it years ago. I believe the reason is no manufacturer wants to admit they screwed up on such an important idea, and be faced with possible recalls from the GDI engines carboning up with relatively low mileages.

If they can get by 8 to 10 years, then they can claim they have solved a problem with GDI that just happened to come up after a certain amount of time/miles.

It's like the old 2V Ford engine spark plug ejection. They knew there was a problem that could be easily fixed, but to fix it early and admit a problem meant massive recalls. Cheaper to fix a few under warranty, and let the rest just eventually wear out and be replaced.

Does anyone remember Ford's 3.8 V6 and the instances of head gasket failures, especially in cars that went short distances during heat cycles?

We had one. Ford did warrant certain years and models of it, after they were forced to. The '94 Mercury Sable we had was on it's 3rd engine when I traded it in with 96k miles, and that engine was using water.

I told the sales man what the deal was. and it still had a day or two of warranty left, so get it in their shop, get a new engine, and sell it since it still looked great.

His response was it didn't matter, it was going to the auction....... He really cared. The shop could have made money, and the car could have been sold with a new reman engine for much more.

To expand upon my last post. Ford was forced to recall certain model/years of the 3.8 V-6. Mine started messing up at around 30k miles. I called the mercury dealer about repairing it, and they told me about the recall. By then, I was out of factory warranty on time, and was going repair it myself. I just wanted to know if there were any improved parts.

They asked for the vin, and told me my car was under a TSB/warranty, and could get a 100% free engine install.

The replaced the engine with a re-man, that made it about 30k miles, then replaced that engine, that was using water around 30k again. I was going to have it fixed again, but the wife wanted a new vehicle, so I traded it, with full disclosure on the engine, and there was still warranty left for them to fix the car in my name before officially trading it.

They didn't want to do it, or at least the salesperson didn't. The GM may have felt differently.

Now, to the point of this long post......

Both engine replacements, from me dropping off to picking up, was less than a week, including them ordering the engine after I dropped off the car. Usually dropping off on Monday, and picking up late Thursday or Friday that same week.

My, how times have changed......

BTW, The problem with those engines was the bolt holes were too close to the cylinders and water ports, and it being the early days of aluminum heads on cast iron blocks, they didn't have good gaskets to help out any.

They claim 15% more fuel efficiency direct over port injection, of course port injection doesnt get lspi as the fuel doesnt get injected until it's ready to burn. So 15% surely doesnt mean 15% better mpg, perhaps none at all. You can always have opted for less HP but a more reliable engine with PI? There is a reason they chose DI, and the same thing with EV, they dont want automobiles to last period stop. The United States of Japan, we gonna get those engine replaced at 50k miles, just wait.

Optimal mode combustion for liquid fuel is stoichiometric when loaded (rich burn), lean burn at light loads.

Therefore, 2 fuel injector locations are needed for gasoline. Using the direct injector for rich burn is like using a choke from old times - there's not enough time for all the gasoline to vaporize when direct injected to burn. So there's lots of umburned gas and soot leftover.

Why? Because you can't directly inject gasoline at the high pressure needed to vaporize all of it in a short timeframe. There's no lubricity in gasoline for the pump or injector, and it has dangerously low flash point.

So you need a port fuel injector for rich burn, gives fuel time to vaporize during intake stroke and compression stroke. This time is entirely missing during direct gasoline injection

There aren't any of these limitations with diesel fuel, so they're injecting over 30,000 psi these days.

If you stay on top of your oil changes,the Hemi isn't really known to have internal / crankcase sludge issues Mike.
