amsoil vs conventional oil

[DRH1175]

What will make my vehicles last longer. I currently am using amsoil in all of my engines. Though the bottle says I can go 25,000 miles I am anal about oil changes. I have my vehicles on a 7500 mile change interval. I also use the Amsoil EA filters. Question is am I getting better protection on my engine than if I was to use conventional oil and filters and a 3000 mile interval. I always change both the oil and filters at the same time at 7500 miles.

Well depending on how old your car is most newer cars are 5000 miles on the oil. You should be able to get double the service with amsoil or any synthetic.The 25,000 mile thing I belive is if you get a test done done on it. I run synthetic in everything I own, skid steers, trucks, the wifves mini van, All small engines, hydro pumps, trannys, rear ends, Everything is synthetic.

AMSOIL has a couple of families of full synthetic motor oil.

The XL series (sold mostly in quick lubes) is rated for a 7500 mile oil change - normal or severe duty.

AMSOIL's traditional family is rated for up to 1 year or 25,000 miles of normal driving; or 1 year or 15,000 miles of severe duty driving. Most drivers come under the severe category.

AMSOIL will increase fuel economy, typically 3% to 5% while decreasing engine wear 50%.

Most drivers come under the severe category.

Why is this?? I don't consider driving to work every day severe driving?? Most people out there aren't towing every mile, or going down a gravel road with a fully loaded one ton truck?? Just curious why you say that most drivers are sever duty.

Severe driving isn't just towing or heavy hauling. It can be frequent short trips where the engine may not get up to temp, a lot of stop and go driving, living in a cold or hot climate as a couple of examples.

Yatta yatta yatta with the fancy-schmancy oil thing. Fancy oils and "special" treatments have been around about as long as the internal combustion engine. In more than fity years of running boats (big) trucks, airplanes, dozens of vehicles and so many outboard motors I can't recall all I have ever used is the reccomended old prehistoric petroleum that comes ouf of the ground.

Guess what: never had a seized engine, frozen ring, bent rod,cracked block or impaired smadler extension.

I guess some synthetics are fine....but the old stuff is okay and waaaaayyyy cheaper.

Thank you and good night.

I agree with you ufatz. I am in sales and sales and engine oil is one thing I sell. Synthetic oil is the best oil you can buy for a engine equally important is a high quality filter. Being that I have worked in a machine shop rebuilding engines I can say that I might now a thing or two about the business. Marketing is the name of the game with any product. If I tell you I can sell you a awesome pair of underwear that can make you feel 20 years younger and 30 pounds lighter wow do I have a great product. Now in order to make my sale I have to prove myself. Now I have a problem. By the way I wouldnt use Amsoil in any of my engines but thats just my opinion!!!

If most drivers come under the severe category, wouldn't that mean that "severe" is actually "normal"

I would agree with that statement also, BUT, when my vehicle is only running about 10K-12K a year, I'm still money ahead doing a yearly oil change with amsoil that's guarenteed for 25K, than I am doing 4 oil changes with conventional oil!! Amsoil is expensive, but worth it to me in my situation. I only run one of my 3 vehicles with it, the others go conventional, or synthetic blend, and I change them myself.

I would have to agree with you on that one

As a mechanic, the biggest problem I see, is that when people go to extended intervals for oil changes, they often tend to overlook checking and doing the other things like greasing/lubing things that should be done in between those longer intervals.

[jwhjr]

Macgyver55 makes an excellent point. I just changed my oil yesterday on my truck after 8 months and a little over 12K miles (I had Amsoil 25K oil/filter in it). In between the 2 oil changes though, I made sure to check the oil level every couple of weeks and ended up adding roughly a half quart in that time. I also rotated the tires twice and greased the chassis as well. Even though I go longer than most for oil changes, I make sure the oil level is always good and do the other maintenance in-between changes that is necessary.

My understanding is that conventional oil breaks down after time, that is why they recommend 3 months or 3000 miles. Synthetic oil does not break down, it only gets dirty. You supposedly could just keep filtering synthetic oil and keep re-using it. I use synthetics because we only put about 9000 miles a year on our car and my truck only gets about 4000. For me its a no-brainer to only have to do 1 oil change a year on each vehicle. I think its easier on the vehicles in the winter with the synthetic oil to.

Good point Macgyver55. No oil or any interval ever excuses anyone from regular checking. There are too many "gas and go" people who never check anything - and it doesn't matter what type of oil or interval many will eventually get in trouble because of it. How many don't even know how to open the hood or check any fluid levels?
