For Your Class C Motorhome
The many synthetic oil advantages over traditional non-synthetic oil is well documented, but not well understood. Synthetic oil has been around since the early 1970s and has been proven to extend drain intervals. (A drain interval is the length of time between oil changes.) The longer that you can extend a drain interval, the more cost effective the oil becomes, and you will have less environmental impact issues.
Let's get a bit of history under out belt, and then we will better understand how significant the synthetic oil advantages are when used in our modern high performance engines.
At the turn of the 20th century and up until the mid 1930's the oil used in automobiles was primitive by today's standards. In fact, the average drain interval was between 500 and 1000 miles.
Filters were non-existent to primitive. The viscosity on an oil was fixed. Therefore, oil changes were dictated by the seasons due to the change in the ambient temperature.
It was not until the 1930's that improved filtration and oil additive technology was developed. This state of the art technology allowed drain intervals to increase to between 2000 to 3000 miles.
The 3000 mile oil change has not increased significantly since that time. Oil has improved, but drain intervals have remained the same. We are talking 80 years without an increase in drain intervals!
The war effort of the 1940's produced the formulation of multi-grade oil that stabilized the drain intervals at today's levels. For the first time, an oil change could extend through a cold to a hot season. This solidified the 3000 mile oil drain interval and freed us from the seasonal oil changes.
However, with the introduction of synthetic oil by AMSOIL in the early 1970s, there developed a significant synthetic oil advantage over traditional non-synthetic oil. AMSOIL claims a drain interval of 25000 miles. They have stood behind this claim for over 30 years. It should be noted that some traditional oil manufacturers have stretched the oil change interval to 5,000 miles, but this is still 1/5 the time achieved by AMSOIL.
There are also manufacturers that are now using a computer monitoring system to tell the owner/operator when to change the oil. This system analyzes the oil; and when it determines that the engine oil is no longer suitable for lubrication, it signals the operator to change the oil. I'm thinking that this is a good tool to maximize the synthetic oil advantage.
Interestingly enough, when the other major oil manufacturers got into synthetic oil production they still recommended that the automobile owner abide by the manufacturers' recommended oil change schedule. Most auto makers want you to change the oil every 3000 to 5000 miles.
So, what's the deal? Are we to listen to the automotive side of the house that feels very safe limiting oil drain intervals to less than 5000 miles? The auto manufacturers certainly feel justified in this. Warranties are expensive and everyone wants to keep costs down.
have extended oil drain intervals significantly. But it would appear that the automotive manufacturers and major oil companies
have other priorities.

So, what is keeping us from benefiting from the obvious synthetic oil advantages when it comes to protecting our very expensive Class C Motorhomes? Let's look at some myths that may help clear up things a bit.
Help Our Environment?
Let's look a little further into the synthetic oil advantages and how they relate to the positive effects that an extended oil drain will have on the environment.
Unfortunately, many people think of motorhomes as being gross polluters. This issue can be easily debunked, but I'm not going there on this page. I only bring this subject up to point out a very narrow aspect of pollution that can easily be avoided.
In the United States, the number one polluter of our fresh water is motor oil. The Environmental Protection Agency claims that "Improperly disposed used oil is the largest single source of oil pollution fouling our nation's waters."
Well, that's a pretty clear statement! The API says this adds "up to 200 million gallons of used motor oil... dumped every year down sewers drains or in the ground." API also reminds us, too, that "A single quart of oil can foul thousands of gallons of water".
Let's look at the above quotes a little bit. I'm sure that there is motor oil pollution getting into our water. I'm not sure how the exact amount can be determined, but I'm not a statistician. I will say that 200 million gallons seems to be a bit much. I remember reading somewhere the 98.5% of the time statistics are just made up!
I'm 65 years old, and way back in 1970 I saw a person change his oil by dumping it down a drain. That was just once a long time ago, and even then it was looked down upon. Some things just don't make sense.
Anyway, most people, especially motorhome owners, have their rigs professionally serviced. I do change my own oil, but I recycle it through the county.
Unfortunately there is the perception out there that motorhomes pollute. What I want to point out is that if we can extend our drain intervals with the use of a good synthetic oil, maybe we can help present a positive side to the concerned environmental citizen.
