if you can have the confidence in the oiling system and take the effort to learn the alarms and how things can go south like racer said..... then you KNOW life will be a LOT easier than trying to mix your oil with the gas as you pump it..... I do it now and man would i love to NOT do it.....out there on cold dark mornings getting the funnel and the oil and guessing what ill need for gas and putting that much oil in first( so the gas can wash it down into the tank) and then doing it again....when i think the tank will take more gas....... maintain the oil level alarm and the oil flow alarm..... although Ive had alarms go off on my motors when nothing was wrong......so...its a confidence factor for believing the alarm, or lack thereof!
