Great tip Jonathan. Soon after I bought my "new" 300CE I had all the fluids changed, including the oil. I decided to try Mobil 1 synthetic oil and I was surprised when the check oil came on a few weeks later. Turned out that the car was low on oil. After that I kept checking the oil and consumption was high. I called the PO who swore that the car did not use much oil between changes when she had it.

Last oil change I went back to the dyno that had been used by the PO with every oil change in that car -- Castrol 20-50W.

I've gone 2k miles since going back to Castrol and the oil level at the dipstick has not gone down. Those 2k miles include some high speed driving to Monterey, CA and back.

I may try the oil you found, but I would probably stay with what has worled for that car.
