Engine oil

This is my OWN opinion and reflect what I think.......

Many here seem to be Toyota fluid big fan I see no problem there and it is what Toyota recommend. If there was no problem I will tend to ask my self why not there oil since it is cheap....but a bit of research and i see to many Prius engine who consume oil for my taste. So far noting really proof oil is the cause but 0w20 is a watery oil and need to be very hight quality to lube well. I will not wait until Toyota or someone else find maybe it was not the best. There is other brand but I think one of the best oil specialist manufacturer on the market is Amsoil so 0w20 signature will be my next oil for my Prius and at least if I have oil consumption later on I will know I did all what I can.

 

Mobil makes the Toyota oil, so you can pay $23 for 5-quarts of Mobil1 at Walmart or you can pay the $7-10/qt your stealership charges. Any good brand name oil with the same endorsements for quality should work.

 

So Toyota 0w20 is in fact mobil 1 0w20 full synthetic? If so Mobil are known to offer decent product Pardon me I dont doubt what you said but how do you know it is exactly the same? If so maybe Europe and Asia use a different brand so it will be nice to see if japanese and europe Prius have the same rate of oil consumption

 

Mobil makes the Toyota oil to Toyota's specs, which may be different from the generic Mobil 1. In any case, I use the Toyota-branded 0w-20 when i change the oil. I don't care too much about the price difference since I'm only changing it (at most) twice a year.

 

It's weird, for me the cheapest oil, by far, is Toyota OW-20 . Up here Mobil or (more prevalent) Pennzoil 0W-20 are both well over $10 (Can) per US quart, and the Toyota 0W-20 is currently $5.91, per liter. That's with a recent uptick in price, for the longest time it was $5.65.

Anyway, all I've used is the Toyota oil, doing my own oil changes every 6 months, for over 5 years now. Seems like a happy car, and consuming no oil. That's actually an anomaly for me, the first car we've ever had that doesn't end up down a pint between oil changes.

 

Yes. You don't run clean oil through a dirty filter.

 

Debatable. Toyota says to, I follow that. OTOH, Honda said to change filter at every other oil change, I'm doing that too, with another vehicle. I make a slight variation to that: remove, drain and reinstall the old filter, on the oil-change-only times.

 

We will have to disagree on this one Mendel.

 

That's the old conventional wisdom, but evidence for it is scant. Honda did its testing. If oil in healthy engines tended to come remotely near clogging filters within a single oil-change interval, car manufacturers wouldn't have gotten by with shrinking filters to ¼ their former size as they have.

 

Do what you want to your own vehicles, but your suggesting the unknowing OP not change the filter with every oil change is dead wrong CR94.

 

if the engine dies & the toyota dealer asks you about oil filter changes, are you gonna tell him about the honda intervals?
a oil filter costs as much as a glass of good beer or a bigmac, so what sense does it make to save a few bucks here?
I'm pretty thrifty (... > prius), even my wife calls me a cheapskate sometimes, but saving on oil or an oil filter: never//

 

We don't know what your options are overseas, but the Toyota seems to be among the best quality oils. I skipped the filter last time but that was the first time I did that.

 

Why?

 

...I take the 5th ammendment

 

Since I'm under the car anyway when I change the oil, I always change the filter as well.

 

Here I thought I was the only cheapskate.

 

Makes sense to me, a filter is not expensive.

 

That's not fair, you MUST take a position.
