For those of you who missed the memo, and since Mobil won't fess up to it... Delvac-1 is now sold as Mobil-1 'Truck & SUV' Formula but a lot cheaper. Usually $5/qt, or if you're willing to go to the Evil Empire, Mall-Wart has 5-qt jugs for ~$19.89. That's about $3.98/qt for Delvac-1, folks. If you buy D-1 in gallon jugs at the distrbutor, it's usually $24/qt or so. You do the math... but I'm buying mine in 5qt jugs!!
Also, although designed for diesels, the D-1 / T&S is an excellent oil for gas engines too. It has a different base stock than all the other M-1 oils, AFAIK. I use it in my 300E and E500 (and the Ford cargo van too). =) -dm > ------------------------------ > Date: Thu, 25 Aug 2005 20:45:33 -0500 > From: Peter Frederick <[EMAIL PROTECTED]> > Subject: Re: [MBZ] More M1 > > I'm leary of using 0 weight oil in a diesel as I don't think it > provides enough film strength to protect the crankpin bearings on cold > running.
