A person could claim to have been boating for 35 years. How would anyone know?
Nobody comes to your boat to interview you before they let you join.
psneeld thanks for posting this thread.
It was INTERESTING.
I use the block heater (with time clock) for 3 hours before start when temperatures are expected below 40 degrees. My block heater costs $0.15 per hour to run. My truck batteries last 7 years on average because they don't work hard in the winter either. When it's zero out, I can turn the key and be heading down the road in under a minute.....with cabin heat to follow shortly.
With a MPG of 22 to 25, .1-.3 MPG increase doesn't excite me.

You are welcome... you were one of the people I had in mind when I posted it.
In cars and trucks many oil decisions are mandated by the Air Police.
Our MB Sprinter 3500 the turbo V-6 now needs 0W- 30 synthetic to meet mileage and air police demands, not for engine longevity.
The synthetic is required to put less ash in the cat converter DEF device, not for engine longevity.
Oil change is 20,000 miles, not for engine longevity.
