If you are like most people, you do not enjoy getting the oil changed in your vehicles, and although some of us are do-it-yourself types, doing oil changes is not the most enjoyable or satisfying job. The purpose of this website is to familiarize you with Amsoil synthetic oils, and to open your eyes to what is possible with top-quality synthetic oils. For many years, the mantra passed down from the automotive experts was to change your oil every three months or 3,000 miles. I used to subscribe to this doctrine myself, but since I have become a synthetic oil user, and more specifically an AMSOIL user, that piece of 'wisdom' seems patently ludicrous to me now! Not only that, but I now see what an enormous waste of our limited resources it is, and what an unnecessary impact on the environment it is. Even with conventional oils, the 3/3000 recommendation is overly conservative from an engine protection point of view, but with synthetics, it's plain irresponsible. I have 4 vehicles in my household, so if I didn't take advantage of extended drain intervals offered by Amsoil synthetics, I'd be changing oil in one car or another at least once per month! I don't know about you, but that's not my idea of fun!

Amsoil produces a wide variety of oils that are suitable for just about every vehicle on the road today. Even the newer cars that call for a 5W-20 or 0W-20 oil can use an Amsoil product that exactly matches the requirements set forth by the manufacturer. Amsoil oils are fully synthetic oils that use PAO* base stocks and the highest quality additives available. The high quality of Amsoil's products combined with the physical advantages enjoyed by all synthetic oils results in a motor oil that can protect your car's engine for a minimum of 12 months or 25,000 miles. Combine that with one of Amsoil's Absolute Efficiency oil filters, which can also be used for that same 12 months or 25,000 miles and you only have to change your oil once a year.

Why is synthetic oil better?
Good question! Check out this informational site.

That's really all you have to do. Change your oil every 12 months or 25000 miles and quit wasting time on cheap oil from the quickie lube, or overpriced oil from your dealer, every 3000 miles.

Will using Amsoil void my new car warranty?

No. It will not. Manufacturers’ warranties are based upon the use of oils meeting specific API Service Classifications, for example, SJ/CF. (AMSOIL lubricants meet the current API Service requirements and, thus, are perfectly suited for use in any new vehicle without affecting the validity of the new vehicle warranty.) Furthermore, under the provisions of the Magnuson-Moss Warranty Act, car manufacturers cannot void your warranty for using an aftermarket product unless a mechanical failure is directly related to the use of the product. They can’t require you to get your oil changes at the dealership, and they can’t require you to use products that are only available from the dealership. If a service representative at a dealership tells you otherwise, Amsoil will send them a friendly letter to set them straight!

Isn’t this a lot more expensive? I want to save money, not spend more!

When you break down the costs, using Amsoil is not only easier and more convenient, it’s also cheaper!

Consider the following: most cars use about 5 quarts of oil. If you buy conventional motor oil for about $2.50 per quart, that’s $12.50. Let’s say you get a filter for about $4, for a total of $16.50. If you follow the 3-month 3000 mile schedule, you’ll change your oil 4 times per year, for a total cost of $66.00, and you have generated 20 quarts of waste oil and 4 used filters.

With Amsoil, you buy 5 quarts of ASL 5W-30, for example. 5 quarts at $7.25 is $36.25. An EaO oil filter costs about $16 (depending on the application), for a total cost of $52.25 for the entire year, plus you have only generated 5 quarts of waste oil and one used filter. Add in the other synthetic oil benefits of better performance, longer engine life, better cold-start performance, better fuel efficiency, and much more, and it’s a no-brainer.

Is it safe to switch to synthetic oil?

Yes, you can switch your car to synthetic oil at any time. Synthetic oil is completely compatible with conventional oil, so you don’t have to worry about a little bit of old oil in the engine mixing with the synthetic and causing problems. If you really want to do a through job, buy a bottle of Amsoil’s Engine Flush and use it just before you put the synthetic oil in the engine. As long as you’re being thorough about it, buy a cheap oil filter at your friendly local auto parts store and put it on just before you add the engine flush, then run the car per the directions on the bottle. The cheap filter will catch any large particles that are dislodged in the engine flush process. This step is truly for the more detail-oriented among us, and is really optional; however, it is a very good idea for an engine with higher miles that has always had conventional oil. It will give the synthetic oil a head start in breaking down all that varnish that accumulates in an engine run on conventional oil.

I’ve heard that synthetic oil will make seals and gaskets leak. Is that really a problem?

Some of the first synthetic oils on the market 30 years ago were quite aggressive toward rubber gaskets and seals, and would sometimes make older gaskets and seals spring a leak here and there a bit sooner than they otherwise would. Those early experiences earned synthetic oils an unfair reputation for causing leaks that has persisted to this day. The reality is that Amsoil will not cause leaks in modern vehicles. Amsoil is formulated to condition seals, keeping them pliable and preventing leakage. I always tell people that all seals and gaskets eventually will leak whether you use synthetic oil or not. I have two vehicles with over 120,000 miles. One has had synthetic oil in it since 20,000 miles, and the other one didn’t get synthetic oil until I bought it at 102,000 miles (two years ago). Neither one has any leaks, however I have replaced things like crank and cam seals, o-rings, and valve-cover gaskets at the major service intervals, which should always be done. So, I guess the bottom line is a properly maintained engine will not leak fluids regardless of which oil you use.

Not a do-it-yourselfer?

No worries! Most quick-lubes, independent shops, and even dealerships will allow you bring in your own oil and filter for them to install. If the shop you use won’t allow you to bring in your own oil, find another shop that values your business!
