Engine oil is one of the most important aspects of a cars performance which is why one is expected to get it changed after every 10 to 12,000 miles it has be driven. The better engine oil that you use for your car, the better driving performance one will experience. Not only does it offer a better driving experience but it also maintains the health of a cars engine, which allows it to run smoothly for a longer period of its car life without any problems. Many smaller garages are known to go for the smaller 12 gallon oil changer. However if you own a large garage with regular customers, changing up to 10 car engine oils a day is nothing out of the ordinary. In such cases the last thing you want is having to go to empty out the small 12 gallon oil changer to make sure it has the capacity to hold more oil. The cleaning out process can take a lot of time especially with new health and law regulations stating that engine oil has to be disposed of safely. You would be better of draining out the drainer at the end of the day, rather than during the day as this can have a negative effect on your business. When customers come in to have their vehicles engine oil changed, they want it to be a simple and quick process. The last thing they want is having to sit and wait while you drain out your drainer so that you can basically start work. This is why it is recommended that the larger garages opt for a larger oil changer such as the NOD-18 18 Gallon Mobile Oil Drain.
