Out of curiosity, why would truckers want a 5w oil -- ease of starting? And if 5w is good enough to protect their engines, why would we want 15w?
If this is the case, I'd guess it would be because the huge truck engines are less hard-working owing to their size, and thus can take a thinner oil? Brian On 1/23/07, Curt Raymond <[EMAIL PROTECTED]> wrote:
Am I missing something here? Delvac 1 is NOT 15w40, its 5w40 (five double you fourty). Delvac 1300 is 15w40 but its conventional oil. I personally use Mobil 1 15w50 but thats only because I have easy access to it. -Curt Date: Mon, 22 Jan 2007 22:12:02 -0500 From: "Werner Fehlauer" <[EMAIL PROTECTED]> Subject: Re: [MBZ] Where to get Mobil 1 (was: Zerex G-05) To: "Mercedes Discussion List" <mercedes@okiebenz.com> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; format=flowed; charset=iso-8859-1; reply-type=original Yes, I could certainly be out of date, since I usually buy about 8 gallons at a time, and that lasts a couple of years for me. Actually, I thought the Truck&SUV Mobil1 had disappeared with their last change, since it disappeared from local shelves. But I suspect that Delvac1 will be around a bit longer, as real truckers don't seem to have such short attention spans as car drivers seem to have - hence the maketeers at Exxon-Mobil with their constantly changing numbers and bottle shapes and colors. Also, note that the advertising says that the Truck&SUV is for gasoline engines, Diesels don't seem to be included. Anyway, I wouldn't want 5W-30 in my Diesel unless I lived somewhere North of Calgary. I like the idea of 15W-40 standing up to the temperatures and pressures on my engines! Some of us old-timers remember the gas crunch days of the 70s, when the car manufacturers figured out that by using thinner oils, they could save a few horsepower, and hence improve mileage. I believe the trend to 0W and 5W oils is rooted in this concept, which is a good idea as long as you get rid of the car before it gets too many miles on it. The manufacturers have a vested interest in getting people to buy new cars - not keep them for 20-30 years! Using too "thin" and oil was a big part of the downfall of GM and their 5.7 V-8 Diesel - GM said to use straight 30W, and the gas stations put in 10W-40! It had to be better, because it cost more, right? WRONG! Werner --------------------------------- Get your own web address. Have a HUGE year through Yahoo!
