Hi all been a while since I have posted
I have a problem with my modern diesel engines seems I am using a lot of oil
I have fitted a provent 200's on all my modern diesel engined vehicles
I use the vehicles fortnightly for a 4000 kilometer trip in that time I use about a liter of oil
the oil is being caught in the provent catch can each time I do a trip I end up with 500ml oil in the catch tank under the provent
The vehicle has a 15,000 service interval this is the 3rd CRD type diesel I have owned and this one had 3,000 k,s on the clock when I bought it
I fitted a provent to the other vehicles same problem
I was originally using amsoil euro 5W40 but the cost versus usage I decided to go to a mineral oil the usage of oil diminished dramatically the grade of mineral was 15W40
I started to use the same 15W40 mineral in my older higher mileage vehicle as it was evaporating of the synthetic oil as well in that vehicle
I plumbed the provent with a check valve back to the motor sump so as not to have to check the engine for oil usage as much
Back the the 2013 model I switched from 5W30 factory fill to amsoil synthetic 15W40 diesel oil the catch tank is full again
Last service I went back to a 5W40 penrite low saps oil no difference the catch tank is full again after a trip
when I look at the oil that is coming from the the provent its horrible and I can only imagine what this must have been doing to the engine going back through the crankcase breather mixing with EGR gas then into the combustion chamber
I have also had the EGR valve switched off on all my diesel engined vehicles through a tune of the ECU
I do this to all my diesels having had to rebuild my first modern diesel engine because of this problem
Since switching of the EGR's and fitting the provent's the engines blow hardly any smoke only the tell tale puff under hard acceleration
The engines are still consuming oil not through the engine through the crankcase breather into the catch-tank under the provent
What I am trying to figure out is it the oil I am using or is it my driving style
I usually sit on the speed limit using the cruise control drive fairly conservative to get the best fuel economy which is fantastic just seems I have a lot of oil coming through the crankcase breather
At my next service I am going to use a low saps 229.51 rated 10W50 to see if this controls the oil usage
I did not want to attach the return of the provent back to the sump on the new van or the jeep as I intend intend keeping these vehicles for a long time and looking at the oil that comes from the crankcase breather it horrible the thought of plumbing it back t the engine is not appealing
Any ideas on this would be appreciated
