Greetings,
I recently purchased a '76 240D Automatic. The car has 157K miles on the odometer and has been reasonably well cared for (the first owner for 35+ years was an lady who drove it locally). The car has no rust, is beautiful and really made me want to own and restore it.
Aside from rotten window seals, the car's only issue is oil blow by and associated oil leak. (See video of the dancing oil cap test I recently did).

I just drove the car from the East Coast to the Mid West, over 1000 highway miles, with 2 Bottles of Auto RX mixed with Rotella T engine oil + new filter. I also used Diesel Kleen for each diesel fill up. The car ran well but loses about a quart of oil approximate every 300+ miles.
I plan to run the Auto RX for another 2000 odd miles, as instructed, before swapping out the engine oil but thought I'd ask for any suggestions before I continued on. Should I be worried with that rate of oil loss? Should I top up the Auto Rx in the same proportion as the oil that I replace? All experience based advice is welcome!
