Original cost of OPS1 was $600.00 which we bought last year. We figure we have saved about $2200.00 since we have purchased the unit by not having to change our oil as often.
We finally changed our Oil due to TBN getting low. We replaced our oil with Mobil Delvac 1 fully synthetic. We had 146,519 miles on the oil before Bob did a complete oil change. Bob changes the OPS 1 oil filter every 15,000 miles and sends in a oil sample at that time, he changes the full flow oil filter every 30,000 miles. We spend an average of $60.00 every 15,000 miles for new filters and oil sample. Bob lubes the truck himself and also changes the fuel filter every other time that he changes the oil filters.
