[Healeys] oil choices

[Chris Dimmock]

-10? c? Yep. I don't have to deal with that. That's not a hot climate???.
Isn't the max average temp in Amsterdam 22 c?
That's far colder than a Sydney Winter.
I said. "in a hot climate"
-10 to 22C??? That's cold.
Kees. Please read what I write.
Run your car at 5,500 - 5,900 rpm consistently for 15 or 20 minutes at nominal
air temperate of 38C, and a track/road  temp of about 45c and then we can talk
further about oil pressure and oil temperature.
You might need to move? To test your theories?
I said. "in a hot climate".
It doesn't generally get to minus 10c in a hot climate??
If I ever want advice on driving to the snow in winter, I'll call you.
Hot climate.
Deal?
Sincerely.
Chris

engines have long and/or precious small diameter oil ways. These kind of
engines are at risk. It is not all pressure you need. You also want flow.
