As I said, you should > consider doing some current reading about the 2 viscocities. My thinking is that I would use the viscosity that the manufacturer recommends, which is this case is 5W-30. If you think Toyota is old fashioned, that is your business, but other people should be very wary of listening to your advice.

Believe it or not, the folks who designed your Toyota are very knowledgeable about not only the vehicles they designed, but also their proper care, maintenance, and the products used in their care and maintenance. They are aware of the products currently on the market, and they are more knowledgeable than physicians and self-proclaimed automotive experts who think that they know more about Toyotas than Toyota. My experience with Toyotas goes back to 1978, and I've found that if you follow their maintenance recommendations, the car will last plenty long without having to try to outguess what their engineers have already studied. -- Ray O (correct punctuation to reply)

From: * on 8 Oct 2007 09:11 Not only do you have Mobil-1 spelled wrong, you have the entire concept of multi-viscosity oils backwards. When you shut your hot engine off at night, a 10w-30 oil has the viscosity of a 30 weight, while in the morning, when it is cooler, it has the viscosity of a 10 weight. Your "expert" had better stick to passing out pills and doing digital rectal exams. He, apparently, needs a few more decades to get the multi-viscosity concept correct.

The original poster, Tony Pacc, has "Mobil 1" spelled wrong. I kept the spelling unchanged in the thread's title because I thought it was cute. Tony, there's no "e" at the end of Mobil :-) * (or Asterisk-man), you know a lot about cars, but it's clear that Doctor Haas knows a lot about motor oils and viscosities. Viscosities are his specialty, an area he has focused on for decades. I'm confident Dr. Haas's knowledge of motor oils far surpasses your own. |
