Reusable Oil Filter

That restore oil does not work. I'm on my 4th crankcase of it. It's not cleaning the
build up on the oil rings, like I was hoping for. I have another 5qt container I'll be putting in
to use it up, then it's back to the Mobil oil. It was worth the try though. Only $5 more a container.

I will either get a new short block, or remanufactured engine from hybrid pit.....
I will be less hassle with the whole engine, then just the block.

 

Good choice. I switched over to VRP at my last oil change.

 

Are you speaking of Valvoline Premium Blue Restore Gen 2 or the new Valvoline Restore and Protect?

 

Oil flow is determined by the oil pump, essentially never changes unless the oil pump goes into relief mode. The steel mesh filter flows no more oil than a standard filter in the same situation.
The micron rating is not very good. 35 microns is about like the grains in 400 grit sanding paper. Standard oil filters capture far smaller particles.
Maybe you will find the element never needs cleaning if your engine is in good shape. If it does get filled, it probably isn’t in very good shape, or the air filter leaks.
Nothing is wrong with the way the KN filter fits in the housing.

 

Ever tried the toilet paper oil filter that they sold at state fairs?

 

Valvoline Restore and Protect
I also used 4 oz of seafoam 500 miles before changing the oil 3 times....
The oil was really black when I drained it each time.
When I replace the head gasket, the valve train looked almost new.
The slight brown tint wiped off easily with my fingers.

I was just hoping it would MAYBE clean up the oil rings....
It might be, but likely not enough or fast enough. I'm still using about 1.5-2qts of oil
between changes. Depending on my driving.

 

New or used???

 

Used, of course.

 

index But too wide for Prius and no cartridge type. Not store bought toilet paper.
Frantz is good but where could it be put.

 

When I have an old engine with oil that gets dirty as soon as I run the engine, and I mean really dirty, not just carmel a color. I either rinse with kerosine or fill 3/4 (face it by the time oile gets that dirty that fast, the engine is usually burning) and run it for a while, not even up to normal temp, than drain and check the filter and check the dip after running new oil for 100 miles. It also works in the cylinders if the engine is cranked by hand, but it can be messy - unless you remember how to do it 10 or 20 years later.

 

The oil pump determines the flow. The flow stays the same or the oil pump relief valve opens to let oil flow back to the oil pan, or the oil pump drive shears off. The filters don’t flow more.
It’s good to find a product you like. We each get our choices. I am just saying the theory of increased flow is wrong and why. What they say is wrong, it’s just for sales.

 

If you are worried about societal collapse why would you even own a car that needs oil and gas?
An EV plus solar panels and some small tires is what you need.

How tough is it to stock up on genuine Toyota oil filters? You are not in Russia.

 

With societal collapse having a running car will be impossible for a multitude of reasons, lol.

 

The bit of jargon Mr.Vanvandenburg leaves unspoken here is "positive displacement". The oil pump here is a positive-displacement type of pump, which moves a fixed amount of oil with every revolution.

Some pump types naturally move more when the back pressure is lower, and less when the back pressure is higher. But a positive-displacement pump always moves the same amount with each revolution, so if you know the RPM, you know the flow rate.

But for the pump relief valve. A positive-displacement pump needs one, so if the outlet really gets blocked the oil still has someplace to go.

if it's true that the spring setting the relief-valve opening pressure keeps it closed at all expected engine oil operating pressures, so it would only ever open in some dire malfunction, then the flow will always be determined by the RPM.

If the spring sets a lower opening pressure that can occur in operation, then there could be engine speeds where some flow is through the relief valve, and at those times the overall pump+relief valve combination acts like a non-positive-displacement pump.

I don't happen to know offhand what the Prius pump relief valve opening pressure is supposed to be. The only inspection described in the repair manual is a "does it move smoothly" check that doesn't involve measuring it or comparing to a spec.

 

Since oil doesn't go bad for many years, why not just buy a number of jugs.

A reusable oil filter will not "re-refine" used oil and remove liquid contamination or replenish used up additives.

Nothing beats new oil.
