Pennzoil Motor Oil full syn high mileage
Pennzoil is a top brand in motor oils. The 10w (winter) 30 weight full synthetic high mileage motor oil with multiple additives to protect your engine and last for miles. Remember crude oil never breaks down, the additives (detergents anti foaming agents etc.) in the oil breaks down over time and miles. "10W-30" Motor Oil (example) The 1st number, in this case 10 followed by the letter (W-stands for "Winter") is the weight of the oil (cold at start-up) when it is at its thinnest/lightest weight, then once the oil heats up in your running engine, the molecules expand the oil to the higher nunber (the 2nd number) in this case 30 which is the heaviest weight of this oil, so the oil at cold start up is 10-weight, then once heated to operating temperature the weight of the oil becomes 30-weight. "10W-30"

Generator oil use
We lost use of our house on 2/24/2025 due to a severe windstorm that blew over a 150' by 4' wide spruce tree onto our residence taking out electrical service and also water as only well water. We had to purchase a generator and having to run it still to this day, the oil has to be changed after every 50 hours of use. we find this oil works the best and is a good value for our continued usage until power is restored hopefully in near future.
