Triumph TR4, HDEO?

I'm helping someone get a TR4 running, and I decided to use Delo 400 instead of regular 30 weight in this motor. Good choice or no?

Very good choice. Any of the popular HDEO 15W40 will do a good job in the TR4. Nice old cars.

Agreed. I had a '65 TR4 and it loved 15w40 HDEO. Delo 400 would be my first choice.
