Stick with the recommended 20/50 oil.Remember this oil also provides lubrication for the gearbox.

I would suggest contacting Millers Oils as they have a large classic range. There is a 20/50 specifically for when engines and gearboxes share the same oil. There is also a high performance version for classic Minis, CTV 20W50, that might be suitable for high summer. Also think about fitting an oil cooler - a Mini specialist should be able to advise you.

Consult an oil grade/temperature chart, but for those temperatures (similar to Taiwan, which can, rarely, go a bit lower in "not summer") I'd seriously consider a straight grade SAE40, which won't get sheared down by the gears like a 20/50 will. I use a 50:50 blend of straight 40 with either 15W40 or 20/50. as a compromise. 20W50 is getting hard to find here in Taiwan but high quality 15W40 is still used by big trucks.
