I have no idea what the viscosity was, I could ring the oil company (Aegis) to find out what Aegis Gold was, but the owner had just joined **** Johnson at that stage after leaving British Touring Cars, and his father was still running the company. I put it in a motorcycle that is supposed to take 20/30, and am not likely to have put something thin in....back then 5W50 was common for synths here. It was ridden around the block a couple of times, and then put away until a couple of years ago, so hardly used which is why it went in the mower.
I've just done a crude viscosity check at shed temp (20c), and the 5W30 went through in 38secs, the other 63secs, so at that temp it's pretty thick. This has got me wondering about my aircooled motorcycles...thick or thin, more heat into the oil, or less?
