Hi,
It's been more than a month now since I've got hold on my new car: a year 1996 Mercedes-Benz C250 (W202) Turbodiesel. 270000 kilometers, automatic transmission.
This is the OM605 engine, inline-5 cylinders turbocharged indirect diesel injection, with a Bosch electronically controlled inline injection pump.
First, I changed oil -- the car made low miles in its last years by the previous owner, so the oil was like 4 years old -- and filter with some cheap A3/B4 15W40 oil (grocery store brand). A few days before I fixed a vacuum leak preventing the turbo wastegate to be closed, and all the exhaust tract was filled with soot ready to be puffed off the exhaust, so it took a good stroll to get rid of the majority of it.
The engine sound, at idle and on drive, is now smoother. But I want to change the oil again (and change my habits haha) and run a "quality" oil.
I can shop Shell Rimula R4 L 15W40 (link) for cheap (around €30 for 5 liters, it's cheap enough), Shell Helix HX7 10W40 (about the same cost), and Shell Helix Ultra 5W40 (€35)
I live in Reunion Island, where the temps at night won't go below 10°C. I like the idea of running a 15W40 if possible in the long term. I'm now running WVO at 80% and planning to do some mods (more fuel, alter timing, and maybe try a little bit more boost but I don't think that would be worth it with WVO and stock pump internals and injectors).
I might short-trip but I'll do a fast road for 30 minutes almost 3 days a week. I don't plan on extending OCI and what I plan is like 10000 kilometers OCI.
Would you go for Rimula R4 L 15W40 (which has MB-Approval 228.31) or Helix HX7 10W40 (229.3) or Helix Ultra 5W40 (229.5, 226.5) ?
