OK so my late June build CRD that I got in Sept. has an issue with going thru lots of oil. At 2700 miles it was almost off the dipstick low so had the dealer top it off, then at 5000 miles the same and again at 6000 miles. This was all at the dealer. Now it is at 11900 and same spot, but it did last longer (mind you they overfilled it last time- it won't hurt comment made). Now the last two times I got the CRD back with the reminder sticker in the window for 3k miles... Each time pointed out that the change interval was 12.5k and asked the ast. svc. manager if he was sure they used the right oil because the sticker tells me the guy knew nothing about the CRD. I was assured it was but they are "used" to writting 3k.
So today when I dropped it off I had them check the oil SKU on the previous work orders againts the actual oil, of course they have been using 15W40.
I have had no other issues with the CRD and solid mileage (24-26mpg at 75-80 mph)
My question is what if any issues would the wrong oil have caused? Will engine life be affected?
I have this all documented and of course the dealer will call me later today.
What would you folks do.
Oh yeah, it it still keeps on going thru oil like crazy it will be lemon lawed. I bought the CRD as I'm a regional sales manager on the road for 40-50K a year and do not want to worry about the darn thing breaking down, My truck was at 178K and 5 years old so felt it was time. The week after I got te CRD my old truck ended up getting a new engine with a 3 year/unlimited miles warranty so I've actually been using it more because of the oil consumption on the CRD...
