#1745 of 3299 Oil Consumption
Jun 03, 2002 (11:14 am)
1999 Isuzu Trooper Auto/TOD 52k. Havoline 10W30
Folks, My truck was previously burning around one quart every 2,000~2,500 miles. I recently added an engine oil cooler and began using a Puralator pure one filter. My oil consumption has gone down to one quart every 5,000 miles.
I recently studied oil properties and characteristics. It is my personal opinion that the source of most engine oil loss is due to engine oil vaporization above the heads upon which the PCV valve picks it up and burns it. If you keep your oil clean and cool it will not vaporize, thereby reducing the oil loss. Synthetics have a higher vaporization temperature thereby allowing them to have a lower loss as compared to petroleum oils in the same engine.
Therefore, if you have a cheap oil, or even a reputable oil, but with a low vaporization temperature, and you push your engine hard, especially in a hot environment, high oil loss will result.

When I switched to Mobil 1 I went from 1Q ever 2K to 1Q ever 5K in my 2000 AT TOD

3 Trooper's since 96 (2000 was stolen) and never had an oil burning issue. Change my oil every 3K/3mos and use Castrol 10-30w. At most, maybe 1/4 qt. between oil changes if I am doing a lot of freeway speeds (trips w/300-400miles a day). Generally remains right on top. Maybe there is something to this vaporization issue?
#1748 of 3299 Update on brake noise
Jun 03, 2002 (5:51 pm)
Thanks for the prompt responses. Anyway, I made closer attention on the noise and it turned out that in 9 out of 10 the brake noise came from other cars. My real brake noise only came about once or twice per day and sometimes none at all. I will eyeball the pads on next tire rotation.

Anyone know what the front warning sound that is made by the metal shims for the pads? I'm pretty sure I'm on them as they are making noise. Also how did the people who ordered pads from St. Charles go about it and how long did it take to get them?
#1750 of 3299 brake sound

Paisan - It's a high pitched metal-on-metal sound that comes on only when you put on the brakes. The best way to verify that it is the brakes is to step hard on them and release them. The noise should coincide with you stepping on the brakes and goes away when you release. It was pretty obvious when it happened to me.
#1751 of 3299 Brakes.........

I just called up and odered them with year/model with the guy at St.Charles. They are very helpful and I had them in under a week IIRC. There is a difference in price for front and back. I ordered both and have them in my reserve stash with my air and oil filters and extra fuel filter.
#1752 of 3299 Interesting

Mine makes a racket when I'm not on the brakes, and grinds pretty bad when I'm on them. I'm gonna order pads and pull the wheel tonight.

I ordered my brakes by phone and got them in three days. The shipping was free and St. Charles uses FedEx ground. I think I paid $44 and some change for just front pads. I too thought my pads were going (since I now have almost 50,000 miles) and ordered the new ones without even checking the old ones. When the new pads came in I went out to do the install and to my surprise found that the old pads still have 60% or more of their life left. So I put the old pads in the "Some Day in the Future File" and that was that. I did however notice that the brake fluid level was pretty low so I added some additional fluid.
I would recommend that you check them before you change them.

Interesting. Mine are grinding pretty bad, so if it's not the pads themselves, then it is a bad caliper or a warped rotor I'll order em and see what happens.
