You are about to learn a full-proof method of comparing all the major brands of synthetic oil and determine for yourself which one can really call their synthetic oil the best. First of all lets make clear there are no less than 100,000+ pages on the internet tackling this very same subject and if you really do enough research on this subject I’m presuming you will come to the same conclusion I did and that is there is no clear cut winner. Why? Because every single article on the internet is merely offering an opinion and that opinion is usually whatever oil that person is using.

Let’s clear up a few facts no one can dispute. First, most of the articles on the internet at some point all say the same thing and that is everyone should follow their vehicles manufacturer’s recommended drain intervals or follow your oil life monitoring system. If we are going to do that let’s make that drain interval 7,500-miles, this is a safe interval that most will agree the top selling synthetics on the market can safely handle. With that being said the top 3 ways to determine the best oil are;

  • Measure engine wear
  • Used oil analysis
  • Fuel mileage comparisons

Lets take a look how this plays out:

#1: For a practical test lets take the top 7 selling synthetic oils on the market pictured at the top of this page. If we then took 7 brand new identical vehicles (any make or model), installed a different brand of oil in each one then proceeded to drive every vehicle until they all reached 200,000-miles while changing each vehicles oil every 7,500-miles you would see very little difference in performance or engine wear if we followed a normal preventative maintenance schedule.

Speaking of engine wear this always the ultimate method to establish which oil is really best, but other than a highly trained mechanic how many of you are going to pull apart an engine and check every part for wear? Let’s face it no one is going to do this just like it is highly unlikely 95% of you would never keep a vehicle much longer then 200,000 miles anyway. So the question is; does it really matter which brand of synthetic oil you should use? Keep reading and I think you will see why it does matter in the long run.

#2: If we were to pull oil samples every 15,000-miles or roughly once-a-year during our 200,000 mile odyssey there would be a negligence in wear metals with all 7 brands. Again the question is how many of you are going to do this let alone even know how to do it properly. More than likely unless you are a die-hard motor head my guess is less then 5% of most people aren’t going to fuss with pulling oil samples so now off to the final comparison.

#3: Fuel Mileage, this one is easy and anyone can do it. Why fuel mileage comparisons? Simple; in order for internal engine parts to overcome the resistance within the engine itself there has to be a film of lubrication between all moving parts. The resistance this film of oil gives is a direct result of the fuel mileage your vehicle will achieve.

The term “horsepower” was adopted in the late 18th century by Scottish Engineer James Watt, but you don’t have to be an engineer to calculate your fuel mileage, it’s a simple 5th grade math problem of dividing the gallons of fuel used into the miles driven. Less resistance by the oil in your engine will not only increase HP it will also increase the efficiency in which all internal engine parts have less to overcome thereby propelling your vehicle further down the road with less fuel needed to convert to energy. Simple enough.

Why does all this matter and is it really worth it to go through all this trouble to determine which brand of synthetic oil to use? Well if saving a substantial amount of money on oil changes over the course of owning your vehicle (remember we are keeping it for 200,000 miles) and saving even more at the fuel pumps then yes it does matter. If money isn’t a factor for you and you can care less about your fuel mileage then just pick any synthetic oil on the market, you’ll get your 200,000 miles and move on. If however you are interested in squeezing every last value out of your investment I would encourage you to take a strong look at Amsoil Signature Series Motor Oils.

Why Amsoil? First and foremost, longer drain intervals. Amsoil has been formulating 25,000-miles/1-year oil changes since 1972 so its safe to say we know what we are doing. Amsoil also makes a 10,000-mile/6-month oil change for anyone that is a little more conservative and would like to have their vehicle inspected twice/year. What you will pay for either one or two oil changes a year is relatively close to other synthetics except you aren’t sitting in line as often at the quick lubes.

The big payoff is the increase in your fuel mileage that adds up through every week and month of the year. You know how much you spend on fuel every month so how much would you save if you did one less fill-up every 40-days or so? Just 2 more mpg on a vehicle with a 15-gallon tank that’s 30 more miles out of every single tank. Presuming one fill-up/week that’s an extra 120 miles per month you can drive on the same amount of money you spent before you switched to Amsoil.

On average you are looking at saving around $300.00/year on fuel cost and that’s just for one vehicle. You have to look at your total investment of time and money when comparing synthetic oils and not just the price of the oil. Amsoil is an investment up front, however the other synthetic oil companies don’t guarantee a dividend the way Amsoil does plain and simple. Make the right investment with Amsoil and if you are going to run your own test make sure Amsoil is always the last oil you test. Why? Amsoil uses the most expensive additive packages in all their formulas and if you test Amsoil first the residual leftovers in the engine temporarily are passed onto the next oil in that engine giving false results.
