This may have been the first blog post I should have written because the best seller of ours is also the one which sets the benchmark for the industry. Although the AMO 10W-40 was AMSOIL’s first product, the 5W-30 is certainly the most popular and of course the one which has had the most scrutiny.
AMSOIL’s Signature Series 5W-30 is one of the only 100% synthetic lubricants widely available on the market. Once you know about it and the finite details of it’s capabilities as a lubricant, problem solver and time saver there’s no turning back!!
Basic benefits include:
- longer engine life
- Unparallelled protection under the most extreme conditions (Saved repair costs).
- Better fuel economy
- Saved time (up to 25,000 mile intervals or 1-year)
- Saved money – Less stops for service
- Warranty Secure
- Faster Warmups
The main feature of the Signature series line trumps all the benefits in my opinion and that is performance. You can actually tell a difference when running this oil over any of our competitors. The reason is simple.
Nothing is held back in the additive blend for this and other Signature Series products. This is why it’s the best in the industry. I’ll quote AMSOIL’s Vice President Dean Alexander, “When selecting additives and base stocks we are the only company who avoids making decisions based on cost. If there is a better product or a trend for something better AMSOIL is known in our industry to be the first to get it to the consumer with our legendary blending experience. That is our business, the business of being the best, not turning profits for share holders.”
You can print out the data sheet which follows this link to see the properties.
One particular use I suggest the ASL 5W30 (ASL is the product code to identify this product) is for older cars which you may not know the history of. Assuming the motor was at one point briefly overheated or for various reasons fuel made its way into the crankcase (in modern vehicles which run hotter than prior decades have more fuel dilution issues than ever before), you need to assume there are deposits. Deposits and the sludge which forms deposits become highly acidic when combined with moisture. This results in acids which are 1/3rd of the cause for engine wear. Only a high quality motor oil like AMSOIL’s Signature Series will neutralize this. There are varying quality levels of the additives. AMSOIL only uses the best performing additives and in this case we are talking about the detergent which unlike our competition, will fulfill it’s duty over that long oil change interval.
In that older or not-so-well maintained engine the AMSOIL Signature Series will halt the expansion of more deposits as well as halt the wear that has resulted from. The product will also significantly reduce the stress on components which the competing petroleum based synthetic or standard petroleum oil has caused. Of course our detergent based engine flush is recommended first to further allow our detergents to have more effect once the existing deposits are neutralized.
So if you can really push a new or good high performance engine to unheard of extremes using our motor oils, it’s really the cars & trucks you really depend on which need this. That 85 Chevy Caviler or Geo Metro can see another 100,000 miles just by adjusting your oil!
Great for high mileage engines. Actually all motor oils should be for high mileage engines but just knowing the fact that one manufacturer would make an oil strictly for that, one could assume the others are not and by that you could assume the oil’s detergents are not up to the task.
Another additive selected from a pallet of 20 or more quality levels is the seal sweller. Again, AMSOIL’s selection is based on the benefit to the customer and not the overall cost or profit margin. (No stockholders – AMSOIL is family owned)
To answer one of the most popular questions – yes, you can use this in any age of motor. AMSOIL is developed so that no compatibility issues occur. The average customer who switched to our gasoline motor oils has about 130,000 miles.
As an AMSOIL dealer we are always excited to hear from our new customers after trying our top tier products. Their impressions serve them as lifelong customers!
