[TR] How often should I change oil in triumph that rarely does much mileage?

[Dave Northrup]

I always use synthetic, which I think makes a big difference.  Valvoline
20w50 full synthetic racing oil.  Has the lubricants for flat tappet
engines.  You can order it from amazon, and get free shipping for the case
(6 bottles)

6 months is what I do.  Whether the car is driven almost never or a lot.

The problem with oil that sits in a car not being driven frequently is that
contaminants that would ordinarily be dissipated remain. It's not anything
that an hours' drive at highway speeds could not remedy. Oil does not "go
bad" otherwise if you simply drive your car for an hour or so on a regular
basis. This i heard from a former GM employee who was in charge of oil for
them and now owns a Corvette restoration shop. Find a nice place to have
lunch and hour away and make some occasional visits.
