Should you not have been able to read your Sunday papers (on 8 April) here’s Quentin Willson’s recommendation in the Sunday Mirror for you:
“Clean up your engine with test for how dirty your oil is
Here’s a neat way to check your oil and engine.
Put a spot of warm oil on Oil Spy’s analytical paper sheet. It tells you how dirty or how contaminated it is and if there’s water or fuel mixed in.
It’s useful for when you’re looking at used motors because it will tell you if the head gasket’s gone or if the oil’s been in the sump for years.”
The Oil Spy team thanks Quentin for his support!
