On the subject of engine cleaning....in a strictly non snake oil sense....can someone (James,CharlesY) suggest a realistic way to go about it,with the lump IN the vehicle...???
In years gone by I would use flushing oil but this is harder to get now and pretty damn pricey too.I had used,on older lorries,diesel,parrafin,kerosene heating oil (favourite) to add to oil and run,then more to flush through.But again,getting pretty pricey and I dont know how EDC would like it,not really understanding its functions as well as I should.Not keen on synth oils,saw too many problems with early ones,dare say they are fine now but I am bigotted that way.What mineral oils have a higher or more effective detergent content?And how to go about using them?Thoughts from the panel.......
