147: finding reason for oil consumption
Since buying the 147 2.0 TS, I've been getting around 450 miles per litre of oil. With the advice of our friends at Opie, I've been using the best makes (Millers, Fuchs, Motul, Gulf) and changing viscosity as I'd thought the problem stemmed from the thickness of oil used. Having changed at the weekend to Gulf Competition 10w60 (which we all know is a good oil and the thickest grade that can be used in a TS) with no impact on consumption, I've concluded that the problem lies elsewhere.
Now, I'm wondering how to find the reason asap. My feeling is it is either pistons or the lambda. I'd like to get a diagnostics analysis which includes a compression test.
Can anyone think of a better way of finding the cause? If not, where would be a good place to go with right diagnostics equipment?
