Anybody try it, Mobil site says it can be used where 5-30 is used, wont void warranty, has same hot temp lube properties and saves 2% on gas, I am going to try it. >Anybody try it, Mobil site says it can be used where 5-30 is used, >wont void warranty, has same hot temp lube properties and saves 2% on >gas, I am going to try it. I ask myself "How can a 0w30 or 5w30 save gas compared with a 10w30 oil? Please follow my reasoning. The 'w' stands for 'winter' and is a measure of how fast the oil flows at cold temperatures. The second number is how fast it flows at operating temperatures. The shear factor is closely related to the flow rate so a 30w oil has a higher shear factor than a 10w oil, meaning that the 30w oil will offer better lubrication and engine protection at operating temperatures. An engine with better lubrication will have less internal friction and use less fuel overcoming it's internal friction. If the above is true then it stands to reason that 0w30, 5w30, 10w30 and straight 30w oil would all give about the same lubrication at engine operating temperatures. The differences would show up at a cold start with 0w30 giving slightly better engine protection upon start up than 10w30. Since your engine only operates at reduced temperatures for a very short period of time, the differences in fuel mileage between the different oils should be barely noticeable. This assumes that you are in the lower 48. I'm not trying to be a smart-a.s, I really would like to know if I'm missing something here.

I probably wouldn't do it, and I'm all for more power and better economy. Unless it is *REALLY* cold where you are in the winter, stick to 5W-20 or 5W-30. This is a good all purpose oil and is probably Toyota's original reccommendation for your car.

I remember before multi grade was out, when 10-30 came out nobody would touch it, since nobody wanted 10W in their motor. ransley <Mark_Ransley@yahoo.com> wrote: Anybody try it, Mobil site says it can be used where 5-30 is used, wont void warranty, has same hot temp lube properties and saves 2% on gas, I am going to try it. ========================= Please warn us when you're going to talk about cars ...ok?

Gawd > ..that's sooo annoying.. How will you know that it is a success? It is very hard to measure power output. And, even if you actually calculate your mileage, you would have to have some way of accounting for different types of driving. An increase from 35 mpg by 2% is from 35.0 mpg to 35.7 mpg. That's hard to messure accurately. You can get a bigger gain by just filling your tires with air. Don't get me wrong: I am going to use it too. But, the difference in mileage is small and very hard to messure in individual cars. However, if everyone did use measures like this, it would decrease our need for imported oil.

He didn't put an {OT} in the header to let us know he was going to talk about something other than total bullshit. >>Anybody try it, Mobil site says it can be used where 5-30 is used, >>wont void warranty, has same hot temp lube properties and saves 2% on [quoted text clipped - 27 lines] > > Jack That is why I stick to synthetics.

What car? Toyota has a list (and Ray posted it here a few months ago) of cars that can avail themselves of this oil. Funny thing is, my Scion can, but a year or two older Camry with the same motor can't...or is it that my Scion can't, but an '07 can? >> Anybody try it, Mobil site says it can be used where 5-30 is used, >> wont void warranty, has same hot temp lube properties and saves 2% on [quoted text clipped - 5 lines] > Funny thing is, my Scion can, but a year or two older Camry with the same > motor can't...or is it that my Scion can't, but an '07 can?

How old is it?!?!? Damn! How many miles on it? Of course, high milage may even be more of a case against using a lower weight oil. It may flow better, but it may not get up enough oil pressure. Unfortunately, a lot of cars aren't putting in oil pressure guages anymore, which may be better, since ignorance is bliss. I cringe when I see the OP guage in the Supra after a long drive on a hot day... Go for it, if you'd like. It would be interesting to see the results... (other than the blown engine, of course! :O ) You own a Volvo? You have my sympathy...(See "Hachi! re:Craig's car" from wickeddoll...) I would like one of these, though... http://www.superiorvolvo.com/blog/uploaded_images/100_9273-773712.jpg http://farm3.static.flickr.com/2203/2408442611_6cc1c7cb26_o.jpg > >> >>> Anybody try it, Mobil site says it can be used where 5-30 is used, > >> >>> wont void warranty, has same hot temp lube properties and saves 2% on [quoted text clipped - 38 lines] > > - Show quoted text - The camry 109000, great motor and trans good for 200,000 more based on pollution tests, but it has body-metal cancer. I dont think the 91 camry was designed for 0-30 and its a spare car going to the hospital. The V40, dealer said ok with 0-30 mobil 1, plus it can go to -22f here. so I will try it. Synthetec in trans and differential and motor I notice more power, the 0 30 will be noticable in power and mpg I think. Yea no pressure or V gauges, but on the 84 series Camry it was normal to show 2lb lb at idle, I put in a gauge, then got scared. >> Anybody try it, Mobil site says it can be used where 5-30 is used, >> wont void warranty, has same hot temp lube properties and saves 2% on [quoted text clipped - 5 lines] > Funny thing is, my Scion can, but a year or two older Camry with the same > motor can't...or is it that my Scion can't, but an '07 can? Both of my cars use 5W-20. I did not like the idea of that at first, but now I am OK with it. My truck uses 5W-30 and that took some getting used to years ago. |
