You have a speck of knowledge but not enough to be anywhere near expert in field of tribology. BITOG are rank amatures and full of misinformation. If you think this is good site you have been fooled. Spend seven years at University maybe you have some more knowledge.

Little Girl, not once have you rebuttaled my posts with counter arguments.

Instead, you do what all people do who are ignorant, and who hate to admit stupidity, failure, and that's to character-assasinate the other person.

So go outside and drive the car your daddy or BF gave you, little girl...this site is for grownups.

The engine damage isn't a fair trade for a little extra mpg.

5w-20 yes, 0w-20 no

Read the web sites of Mobil1, Pennzoil Platinum, and all the major brands that make 20 weight oil, and even read the labels on their bottles:

"0w-20 wieght oils can be used in any application that calls for 5W-20 weight".

At operational temperature, BOTH 0w-20 and 5w-20 provide the EXACT SAME viscosity. How come you don't understand this?

And where is the engine damage you write of when using 0w-20? MANY UOA's show there is no more wear then if 5w-20 were used.

It seems you have the habit of talking out your a$$. ;-)

Your opinions lack scientific bases, and you use "noise" to determine wear?

People that go to college and learn science know that actually using highly controlled and scientific tests, like a used oil analysis to ascertain wear is far more conclusive.

And if you use noise to decide, did you run your car in a sound studio, and monitor the noises with fined tuned computer monitors? Did you do before and after tests?

Did you graduate from highschool?

Not true in every case, every climite, every season.

The wear numbers I get using 0w-20 versus 0w-30 are the same.

everyone just use what you feel comfortable with . For me , 5w-20 . 5w-30 . No need for insults .

Luser, what part of the Toyota TSB do you not understand? It states do NOT use 0w-20 in the 1.5L

And check these oil threads over the last day or two, I read today where a Yaris owner switched from 5w-30 to just 5w-20 and got back a UOA that had extra wear metals.

Don't know why you keep pretending that what applies to the XD 1.8L applies to your Yaris 1.5L when Toyota's TSB specifically forbids 0w-20 in the Yaris engine...yeah, southern Ca sees lots of really frigid mornings, better use that 0w-20 eventho' the TSB says not to.

Don't dispute his UOA, please.

Genius, you're the guy that's using 0w-20 in southern Ca, eventho' the Toyota TSB says do NOT use 0w-20 in our 1.5Ls, under ANY condition. See how well your warranty works for you after you inform the service department that you refused to follow the Toyota TSB guidelines, not to mention your owner's manual, provided that you have any future issues with your motor.

its getting hot in here.... id say use the oil you wanna use.. its ur car..u can use cooking oil for that matter..

What is the meaning of the word rebuttaled?? What year did the Webster's dictionary add ed to the word rebuttal? I have heard of rebut, rebutted, rebuttal, rebutting, rebuttable, and rebutter but not rebuttaled. Your help would be greatly appreciated.

Silverglow is a troll and should be ignored like most ignoramuses causing trouble and being of no benefit to the forum.

I think his advice on oil is bad. He throws "UOA" around a lot, maybe thinking it'll impress, but goes on to hand out advice about which oil to use, claiming that if 5w-20 is approved for use in our 1.5L, then "UOAs" will show that 0w-20 will work even better in our cars. Most people probably know better than to use a viscosity that isn't listed in the owner's manual or in the latest TSB, but SilverGlow doesn't seem to understand it yet.

I agree, re: UOA are not everything. You can still have a massive failure due to inadequate viscosity which would NOT show up on a uoa until the rod is snapped in half or the had bearing seized and spun. And any mechanical engineer or engine machinist worth their salt will tell you noise = wear all else being equal (diesel are another matter). Also engine are designed to retard timing in the presence engine noise over a specific threshold. So thence goes the fuel milage with the water weight oils. I have dsriven fords designed to run on 20W oil and they run fine. I have never seen and engin that will run on a 20W or 30W. The piston to wallclearances are incompatible given most new engines employ slipper-skirt short pistons.

My brothers toyota had same amount of engine noise at idle as mine. And when he put in amsoil high performance oil. He said his car never has idled smoother. All the sound went away. And it feels like the car has more power on the freeway. It could all be in his head but i can say it does idle very smooth and its quite as a mouse on idle. I am very anxiouse to do the same to my car soon as the engine is broken in in a few more miles.

I see that Advance auto parts has Motorcraft 5w20 synthetic motor oil. The price is good...but is the oil any good?

Has anyone tried this particular oil?

Rebutter

How about: rebutterable, rebuttering, or rebuttabler.
