2.3L Ecoboost on Conventional vs. Synthetic Oil

[seasprite]

I think we have a twin scroll compressor? With my limited knowledge, it has to do with the the turbo operates.

I can see why people might get confused

I think many people confuse a twin turbo with a twin SCROLL turbo (which is what our engines have).

Beat by seconds

Very happy to see the 2.3l make it to half a million miles with no serious failures. I’m sure the controlled environment was marginally kinder to the engines than the environments some of these engines are actually operated in, but 500k is impressive regardless.

Yeah, I doubt anyone would be sticking around after replacing the tranny 5 times...

If you use it (I do not), haven't you wondered with all those start/stop cycles on a regular basis, how much raw fuel gets dumped into the cylinders every time, and how much lube is washed away ???
In some way/shape/form it has to affect the oil and how it lubes the engine.

Start/stop has been much enhanced from yrs back, good info in this article. I don't use it but would if it didn't require using Ford's bms .

I saw or read an article (maybe on here) on how many changes had to be made to vehicles because of the ASS. If I remember right they had to add a pressure pump to the transmission to keep line pressure up, an electric circ pump to the cooling system for hvac an stuff.

the complexity added probably erases any gain from the system an then some...or maybe I just hate it. I turn it off, if I'm at a LONG light on a moderate temp day I'll occasionally turn it on but only for those few minutes.

It's all about getting an extra 1 or 2 mpg on the city EPA test.
I accidentally discovered that a tailgate light bar disables the A.S.S. because you plug it in to the 4-pin trailer plug and the truck thinks it's towing a trailer.

Possible. But that's like saying I have a twin brother and someone mistakes you being a Siamese twin. ??

They call it a twin turbo, so do i

To be honest at this point I think I'd give up after the first one. If they can't get the issues fixed by now I have no faith they ever will.

The


On the previous gen Rangers, the alternator charges the battery until it was 100% charge restored, no matter the driving conditions.

The Battery Management system (BMS) on the 5G Rangers is a very sophisticated charging system. The system keeps the battery at 75% charge. The 25% space left is used to turbocharge the battery when coasting or braking. The alternator has a clutch that (de)activates depending on engine conditions.

Cruising or accelerating the alternator clutch disengages and battery may not be charged at all, but when coasting and/or braking the clutch engages, over revving the clutch to dump high voltage spikes into the battery.

This is a simplistic explanation, but is essentially correct. The designers want the engine to stay at RPM as long as possible when coasting / braking when the alternator clutch is engaged to temporarily overcharge the battery.

I don't believe that is it good for engine or transmission life, but that is how the engineers designed the system to work. All for CAFE standards.

CAFE Is what has made cars/trucks today so complicated and computer driven! Sad and good at the same time

It’s using the exhaust pulses to push the turbo quicker, instead of all ports dumping into the turbo it splits the exhaust ports taking advantage of the pulses. Result is less dead spot. There also could be design changes in the impeller to take advantage of this.

Also when you let off the throttle the hydrocarbon emissions spike if the engine slows down too fast. This is one reason why they've been phasing out manual transmissions and for the last 20 or so years if you did have a stick you'd notice the rpm didn't drop much when you let off the gas to shift.

WOW sounds complicated but thanks for the explanation

couldn't agree more

The new 6G Ranger has the option for the 2.7 V6 Twin Turbo. The 2.3 only has a single turbo. Who ever "they" are has no idea what they're talking about.

i never claim to know what i'm talking about

Who and where? I've only see the turbo in my Focus and Ranger documented by Ford as a Twin-Scroll Turbo.
