you have a clear over flow tank?

Yes

Are guys really running 0w20 in their hemi in their late model 5.7? I feel 5w20 was already too watery.

I started out with 5-20 for the first 20k but always a qt of Lucas synthetic additive.But either 0-30 or 5-30.for me.

Question to service manager- does the rav 4 have a dip stick on their 9 speed?

answer- no it's a closed transmission doesn't need service for 100k miles

q- how to you verify it is full from the factory

a- that's a good question..

q- and...

The new rav 4 is direct injection with port and non turbo, which means lspi is possible but less likely then turbo with high pressure fuel.

In other words, they simply don't make stuff like they used to, not even the good ones.

Going to assume you meant it had an 8 speed trans not 9 speed, so far wife's new 25 Rav 4 hev got 37 mpg hand calculated with just 1100 on OD that's 5 mpg better than her 21 Highlander.

Who the hell is going to rebuild their engines just to put higher tension oil rings in? @Wild one excepted, of course.

Anyway, in addition to those things Lake Speed said, he also knows viscosity is a trade off between engine wear and cylinder cleanliness, so I would never use one of those ultra-light viscosity oils the car companies are trying to force down our throats - ESPECIALLY on a turbocharged GDI engine. The cylinder pressures demand a 30 weight oil under load.

So, the old advice about driving your engine warm up has completely reversed only because single injector GDI is a faulty design. Perfect.

One thing Lake didn't mention is using PEA every so often to spray into your air intake (past the MAF sensor) to clean the intake valve stem of deposits from crankcase oil mist thru the PCV valve. It doesn't get cleaned with PEA (Top Tier) fuel because there is no intake port fuel injector.

What a stupid engine architecture! All because Mitsubishi falsely advertised 20% fuel savings with single injector GDI (actual is 5%).

1- right oil
2- use pea cleaner- um hello redline si-1
3- let engine warm up

He missed a couple? One for sure is not putting the hammer down in first gear and in low gears, another lspi antagonist. In general keep load out as much as you can, research load and lspi,

Now, none of those are as good as my list, don't buy a di turbo. Now, the field is at least direct injected engines, even rav 4 and Subaru twins, but they aren't turbo or at least have that as an option non di turbo, but still have high pressure fuel rail, of interest the Toyota cross seams to not be a HPFR, so dam I am really interested in this now. Even though it is cvt, the rav 4 has a closed trans, so maybe the current bullet proof vehicle as best I can figure in my pea brain considering an entry level SUV or cross over is the toyota cross.

@06 Dodge did you guys test the cross or have any opinions on that?


"Engine load" refers to the amount of work an engine is performing at a given time, and "LSPI" stands for "Low-Speed Pre-Ignition," which is a combustion phenomenon where the fuel mixture ignites prematurely in an engine, typically occurring under high load conditions at low engine speeds; meaning a high engine load at low RPMs significantly increases the risk of LSPI happening in a vehicle.

 

[Burla]

For those interested, who knows perhaps every engine is soon to be at least high pressure fuel rails and direct injected turbo or not. But for now if your choice is port injected engine versus non turbo direct injection like Subaru and Toyota is doing, if you can find a non direct injection like in the cross, this is my new friend google ai's opinion on it...

Of note technically port injected can still get lspi, but that is even less of an issue then non turbo di's.

While any direct injection engine, even without a turbocharger, can potentially experience Low-Speed Pre-Ignition (LSPI), it is significantly more prevalent and severe in turbocharged direct injection engines, particularly when operating under high load and low RPM conditions; meaning non-turbo direct injection engines are less likely to suffer from LSPI issues, but still not completely immune to it.

The solution to low speed torque is diesel.

Too bad they f'd that up by adding a mandatory chemical factory to the exhaust. I was at Cummins during the emissions reduction design debate and said to myself this is gonna go over like a lead balloon from a cost and reliability standpoint.

And here we are, 15 years later, with nothing cost-effective to drive at all. Well, they haven't completely wrecked motorcycles yet, but they're working on it and those are light duty and weather dependant.

Meanwhile my buddies 12 valve 2500 is pulling 25mpg's verified and runs like a friggin top. Thing is ancient and is pulling 25mpg. My buddies ford same era on a good day gets 8mpg no lie.

 

[Burla]

Looking up a new wrinkle, apparently you need some good HP to make best use of a cvt. So the critics say the cross's issue is a cvt paired with a low HP motor makes it difficult to appreciate. good comparison versus outback.

that is a great video Rick, never scene that been out 5 years. good find

another reason long term perhaps alcohol is not a great choice in fuel.

Here in corn country, they don't care about wrecking engines as long as they get their government check for bribing state legislators.

10% minimum ethanol is state law in Minnesota for all gasoline except small engines, for which we only get high octane pure gas at an exorbitant price to prevent customers from fueling their on road vehicles.

The best government that money can buy off.

API SQ & ILSAC GF7 for "aged oil" LSPI seems to weed out cheaper SP & GF6 oil blends. He says many current oils already meet higher specs.

My read: must use more expensive magnesium detergent than cheaper calcium that contributes to LSPI.

Important for those of us with turbos + GDI.
Your new engine shouldn't matter as much, Mike - no turbo? Then again, LSPI occurs at "low speed" where there's not much turbo boost, so....?

I was still living in IA when they pressured the state to stop selling regular gas without 10% Ethanol after that was forced on us come winter we saw a nice drop in fuel mileage with 10% ethanol gas...

Yeah….what the nasty gov’t does…just so we can have safe water to drink and air we can breathe….

You'd do well to read up on ethanol fuel prior to making an uninformed cultural political post in a forum of technical experts.
