I have used RedLine exclusively for the last 10 or so years. I became interested when I saw the Penske CART team transferring redline from a 55 Gal. drum to Mobil One quart bottles to keep the appearances of the use of a sponsors' product. I researched the ASTM test results of Redline and made the switch. To this day I don't think anything comes close to their performance on all tests relevent to a performance application. Most endurance teams use Redline. I have used their motoroils and all syn. lubricants with no problems in several Benz and other cars and bikes (a Kubota tractor too). The 300SD just had a timing chain done at 365,000 miles and the mechanic(very experienced with diesel Benzes) commented that the old chain was still good. I try to change oil and filter on that car every 7-8,000 miles. I do the 500E every 3-4,000. The Kubota once a year.

Good information..this is a very helpful thread.

I had my timing chain checked about a year ago and it was fine then.

On my Kubota...been nearly a year, so should change the oil now...is this what you do? Is it annually or a function of the hours its used. Mine has about 50 hours on it now.

My Ford diesel tractor gets an oil change every six months or 50 hours whichever comes first. Sounds like your synched up with both measurements.

Good luck,
