I want to buy oil thermostats for my engines, and I'm looking for information on what type oil thermostats other OSOer's are using ie: thermostats in the oil filter block,thermostats built in the oil cooler, or units added into the lines?
Are you happy with them? What brands?
Thanks your replies would be appreciated.

Freds(Trick Marine's) remote oil filter/thermostat combo. Works well.

Which brand is Tricks?

I am using the Kieth Eickert "Thermofilter" oil thermostat. It is an oil thermostat with an oil filter mount all in one. It works very well, and it was one of the nicer oil thermostats out on the market when it first came out years ago, but since that time there have been some other well made oil thermostat products that are out on the market that work just as well, and are MUCH less in price.

I'm running the Keith Eickert remote oil thermostat. No problems. Works fine.
