Bob,
Summer has been very hot this year, no days under 90 deg. F. since early December in our part of the country.
No racing in summer, the season is just beginning now for the year, our club will have it's 1st track day next month.
I thought that ULX 100 was an American
oil, will have to research further. Costs the equivalent of $US30 for 1 gallon.
