Just got my test results from Finning. 5592kms on Esso XD 0-40 Synth. Just woke up at home after leaving last Thur for River Shiver, and for the life of me I can't recall if I took the sample before or after I changed the oil filter and added oil to top up...on Wed before leaving. Knowing me it is probably after the filter change so I could get the numbers that would be running now, as I am hoping to take it out to 10,000kms between changes, with a filter change and top up around 5000kms. I just put another 2166kms on since last Wed, so will likely take another sample this week and send it in and see if there are any changes: Long hills with consistant high EGT's.

I had no oil usage with the synth when I changed the filter, and no oil useage on this last road trip. I am really starting to like this oil for the 13BT.
