firstly hi all this is my first post but have been following the forum for years
my question is I own a 2007 Jeep CRD diesel it has a Mercedes OM642 engine and the recommendation is to use a oil of MB 229.51 specification
I have been using the AMSOIL European Car Formula 5W-40 Synthetic Motor Oil AFLQT-EA it has the MB 229.51 specification
The book recommended 5W-30 with the MB 229.51 rating being from the Gold coast in Queensland it doesn't get very cold here lucky to get under double digits in winter that's Celsius as well but it gets very hot during the summer months so I decided the 5w-40 would suit the engine better I also have a Mann hummel provent 200 on the engine and its chipped with egr removed
The vehicle has 230,000 k,s on the clock and after a recent 7,000 k run the oil looks like the day I put it in but it has used a couple of litres of oil my old crd diesel Citroen with the same mileage didn't use a drop of oil but I was using a mineral oil 10w-40 suitable for dpi filters
My question for those in the know can I use another higher viscosity oil without damaging the engine I.E. can I go to a 10w-40 the vehicle blows no smoke unless you are really on the throttle looks like its evaporating or burning it when I check the catch bottle on the provent its got 300 ml in it so not going I also run TC-W3 2 stroke in it at a ratio of 300 to 1 could that have something to do with it
the engine feels like new gets fantastic economy
