My owners manual species 5W-20 or 0W-20 oil.  Do I really need to use 5W-20 oil?
 

   You certainly can use a 5W-20 or 0W-20 if you choose to, however you do not need to use a 5W-20 or 0W-20 oil. You do not have to use 5W-20 or 0W-20 to maintain your warranty, even though some dealership personnel may lead you to believe that you have to use a 5W-20 or 0W-20. Your warranty is still valid and has to be honored whether you choose to use a 5W-20, 0W-20 or another viscosity of oil, such as a 5W-30 0r 0W-30 for example. Once you know the facts and the Federal Magnusson Moss Act law you will be much better informed to protect your rights and use the type of oil you want to use.
 

One of the main reasons 5W-20 and 0W-20 was specified for your engine is to increase the CAFE (Corporate Average Fuel Economy) reported to the Federal Government.  CAFE is the combined average fuel economy of all of a vehicle manufacturers product line.  Minimum CAFE levels are specified by the Federal Government.  In order for a vehicle manufacturer to continue selling profitable large trucks and SUV's, which typically have poor fuel mileage ratings, as compared to smaller cars, and still meet mandated CAFE requirements, they must also sell enough of the smaller cars which have much better fuel economy ratings to offset the poor fuel economy ratings of the larger vehicles.  The change to a 5W-20 or 0W-20 oil will allow and an auto companies overall CAFE to increase by a very small amount, typically in the tenths of a mile per gallon range.  5W-20 or 0W-20 oil is a  lighter viscosity than a 5W-30 oil and therefore has less internal engine frictional losses, or less drag on the crankshaft, pistons and valvetrain, which in turn promotes increased fuel economy.  This increased fuel economy is virtually undetectable to the average motorist without the use of specialized engine monitoring and testing equipment under strictly controlled test track driving  when compared to a 5W-30, 10W-30 or a 0W-30 viscosity motor oil.
Note that Daimler Chrysler Vehicles with the MDI System Specify 5W-20 or 0W-20 and that is what we recommend for these vehicles however there are customers using AMSOIL Series 2000 0W-30 Severe Service in this application with excellent results.

Could using a 5W-30, 10W-30, 0W-30 or 10W-40 oil in my vehicle which specifies a 5W-20 or 0W-20 oil void my new car warranty?

 Absolutely not. Vehicle manufacturers only recommend using motor oils meeting certain viscosity grades and American Petroleum Institute service requirements. Whether a motor oil is a 0W-20, 5W-20, 5W-30, 10W-30, 0W-30, 10W-40 or even a synthetic vs. a petroleum based oil will not affect warranty coverage. The manufacturer is required by Federal Law to cover all equipment failures it would normally cover as long as the oil meets API service requirements and specifications and was not the cause of failure.  In addition, the Federally mandated Magnuson - Moss Act states that a manufacturer may not require a specific brand or type of aftermarket product unless it is provided free of charge.  If your dealership continues to tell you that you must use 5W-20 or 0W-20 motor oil and or/ a specific brand of 5W-20 or 0W-20 motor oil, then ask them to put it in writing.  Their position is inaccurate, and, in fact violates existing law.*

Additionally, if there is ever a question of whether or not a particular motor oil was the cause of an engine failure make sure to get a sample of the used oil in a clean bottle, typically 6 oz. minimum. The oil can then be sent to  two independent testing labs for analysis.  This is standard procedure for most commercial vehicles, trucking, construction/excavation and fleet companies and there are numerous certified test labs all over the country.  Remember, a knowledgeable and informed consumer is your best defense against being taken advantage of by a car dealership service center.

*  Note:  If a car or truck dealership, service center or other business states that using AMSOIL motor oil in your vehicle will void your new car warranty, ask for that statement in writing and send it to AMSOIL  technical Services.  If the business won't provide the statement in writing send AMSOIL Technical Services a letter identifying who made the statement, the name and location of the business and what the statement was.  AMSOIL will then send  a letter to the business informing them that their position is inaccurate, and, in fact, violates existing law.  Your name will be held in confidence.

                            Synthetic oil

Synthetic oil is oil consisting of chemical compounds which were not originally present in crude oil (petroleum) but were artificially made (synthesized) from other compounds. Synthetic oil could be made to be a substitute for petroleum or specially made to be a substitute for a lubricant oil such as conventional (or mineral) motor oil refined from petroleum. When a synthetic oil or synthetic fuel is made as a substitute for petroleum, it is generally produced because of a shortage of petroleum or because petroleum is too expensive. When synthetic oil is made as a substitute for lubricant refined from petroleum, it is generally to provide superior mechanical and chemical properties than those found in traditional mineral oils.

 Synthetic oil as a substitute for petroleum-based oil

One form of synthetic oil is that manufactured using the Fischer-Tropsch process which converts carbon dioxide, carbon monoxide, and methane into liquid hydrocarbons of various forms. This process was developed and used extensively in World War II by Germany, which had limited access to crude oil supplies. Germany's yearly synthetic oil production reached millions of tons in 1944. It is today used in South Africa to produce most of that country's diesel. Dr. Hermann Zorn of I.G. Farben Industrie in Germany actually began to search for lubricants with the properties of natural oils but without the tendencies to gel or gum when used in an engine environment. His work led to the preparation of over 3500 esters in the late 1930s and early 1940s including diesters and polyol esters. Another form of synthetic oil is AMSOIL,which is produced at Amsoil Inc, in Superior WI.

In the early 1970s, synthetic oils began to be marketed as a substitute for mineral oils for engine lubrication. Although in use in the aerospace industry for some years prior, synthetic oil first became commercially available in an API-approved formula for automobile engines when the French Oil company MOTUL introduced a commercial ester-based synthetic oil in 1971[1]. Other early synthetic motor oils included All-Proof, a 10W50 polyolester-based motor oil introduced in 1970; Amsoil, introduced in 1972[2] (with a diester-based 10W40 formula developed by Hatco); and Mobil 1, introduced in North America in 1974[3] (with a PAO-based 5W-20 formula).

 Synthetic Base Stocks

Synthetic motor oils have been made from the following classes of lubricants:

• Polyalphaolefin (PAO) = API (American Petroleum Institute) Group IV base oil
• Synthetic esters, etc = API Group V base oils (non-PAO synthetics, including diesters, polyolesters, alklylated napthlenes, alkyklated benzenes, etc.)
• Hydrocracked/Hydroisomerized = API Group III base oils. Chevron, Mobil, and other petrochemical companies developed processes involving catalytic conversion of feed stocks under pressure in the presence of hydrogen into high quality mineral lubricating oil. In 2005 production of GTL (Gas-to-liquid) Group III base stocks began. The best of these perform much like polyalphaolefin. Group III base stocks are considered synthetic motor oil in North America.[4][5]

Required applications

Many vehicle manufacturers specify synthetic motor oils.

• VW 502.00/505.00/503.01 (includes both diesel and petrol or gasoline engines) [6]
• MB 229.5 ( (4G63 engine)
• Honda HTO-06
• Porsche Approval list 2002
• Some Briggs & Stratton small engines.
• Dodge Viper V10
• Ridley Motorcycle Company
• Mercury Grand Marquis (2003 & newer) 5W-20
• Shelby Dodge Automobiles
• Chevrolet Trailblazer SS (2006-2008)
• Cars equipped with Chrysler Hemi engines (2002 & newer)

Various motor oils made from Group III, Group IV, and/or Group V base oils are on the market that meet one or more of these

• Chevrolet Corvette (1997 & newer)

 Advantages

The technical advantages of synthetic motor oils include:

• Measurably better low and high temperature viscosity performance
• Better chemical & shear stability
• Decreased evaporative loss
• Resistance to oxidation, thermal breakdown and oil sludge problems
• Extended drain intervals with the environmental benefit of less waste oil created.

Amsoil Synthetic Motor Oil meets the current SG/CD ratings and all vehicle
manufacture's warranty requirements in the proper viscosity.
