Are there many of us using Mobil DTE light oil?

I changed to it a while back because I heard it was scimilar to turbine oil and but not as harmful . I have now used 400 litres of fuel at 5% in Wrens, jetcats and simjets and I thought I would take a look in one of the engines I have run it in to see whats going on in there and the engine its spotless with little sign of any carbon build up at all. The bearings are also perfect. Its less than half the cost of turbine oil too!
