Message:
hi all i have a 02 QC 4x4 4.7 with about 600 miles on it and was wondering how many people use synthetic oil in your truck and how long did you wait till you switched to synthetic? and is there any benifits to using synthetic instead of regular oil?

Wow, You're gonna get Steven Roark posting here! NOt that that's a bad thing.
Are there any benefits of syn Vs. dino oil?
Do fish swim? Same kinda question. Many different opinions here on the oil thing though. Some will say dino oil, and change it alot.
I"ve used Mobil 1 myself since the first change at about 3K, and a quality filter (WiX).
I have 31K now, and usually go atleast 5K before changing my oil.
YOu're gonna get alot of opinions here, you got my program on my 01, 4.7, 5spd manual.
Do a search here on this site, and make your own.
Happy Motoring! (I think that was an old 'ESSO' slogan)

I've got a 2002 V6, and I did my first oil change at 3600 miles. I put Mobil 1 10W30 in it, with a Mobil 1 filter. I haven't noticed any immediate 500HP gains like some folks report simply by switching oil, but the oil does seem to be staying clean a lot longer. The first time that I checked it after changing, I almost panicked because I couldn't see it on the dipstick. It was still clear, and the Mobil filter seems to be doing an excellent job of cleaning out the remaining OEM oil.

djdusaf,
I have used AMSOIL now for many years in both my vehicles and my companies vehicles and equipment.
I am a former Mobil1 and Redline user and when I first heard of AMSOIL and their "Extended Drain Claim" I laughed my A$$ off.
Well I have "experimented" with AMSOIL over the years through oil analysis, fuel consumption reports ... both M.P.G. and G.P.H.(for equipment with hour meters) and the results are as plain as black and white (their products work as advertised) !
To answer your question ... Synthetic oils last longer, protect better and help engines run more efficiently.
Dr. D
P.S.
I switch over to synthetics after 1,000 miles or 50 hours(engines with hour meters) of engine operation just to make sure that their are no problems to start with.

I've used Mobil 1 in 5 vehicles over a total of 20 years, 3 of the vehicles went to well over 100,000 miles, the latest 2 now racking up the miles quickly. All 5 were started on the Mobil 1 at about 1,000 miles to allow for engine break in. Never any problem at all with oil consumption or burning over the life of the vehicles, even on the very high mileage cars.
I've never really worried about checking to see if it increases mileage or HP. I've seen documented tests that says it does help, but the main reasons I love it are:
1. The engines stay EXTREMELY clean internally, no sludge buildup on the valvetrain, etc. And I've had mechanics even comment on that with my cars after 100,000 miles. One mechanic even called me back into the garage area to point this out to me during a routine valve adjustment maintenance visit. He commented about how clean the valve train was and he asked what kind of oil I was using.
2. Very easy start up in very cold weather. It gets pretty cold around here (it was -2 F this morning) and the engine always spins over MUCH easier for starting with synthetic oil vs. conventional oil. You don't hear that RRRR-RRRR-RRRR slow grinding sound when trying to start the engine. It just spins over and starts.. Easier on the starter motor and battery.
Can't speak for any of the other synthetics though. I've always used only Mobil 1.

Most major brand name petroleum oils perform adequately provided your driving conditions are normal and provided you change the oil regularly per manufacturers recommendations, (Note: short city trips, dusty conditions, HARD driving, and towing are considered extreme). For those of you who drive your vehicle hard, tow a trailer, drive very short distances, sit idling and in stop & go traffic for long periods, live in a cold climate and/or if your car runs hot, etc., etc., etc., ... quality synthetic motor oil, synthetic gear lube, and synthetic automatic transmission fluid is a wise investment that will provide the additional protection that you require as well as last thousands of miles longer than conventional lubricants.
----------
Synthetic oils were originally developed more than 50 years ago. Amsoil introduced the first synthetic oil for automotive use in 1972 and have continued to be at the leading edge of development ever since. Mobil 1, undoubtedly the most recognized name in synthetics, was introduced in 1976. Many companies have jumped on the bandwagon and have since released synthetic lubricants for automotive use and all are becoming increasingly popular for their superior lubricating properties, superior ability to flow at cold temperatures, and their ability to withstand high temperatures for extended periods of time. Several new cars are delivered with synthetic oil in the crankcase and require synthetic oil use throughout the life of the car.
----------
There are two primary differences between synthetic oils and conventional petroleum oils. These are the base stock or liquid that makes up the volume of the oil, and the additive package. There are additives (not to be confused with over the counter additives) in all oils that enhance the wear resistance properties of the oil, enhance the ability of the oil to neutralize acids and combustion by products, and provide corrosion protection for the engine’s internal surfaces. The amount and quality of these additives vary from one oil brand to another and this is a very significant factor in the ability of an oil to adequately protect your engine in all driving conditions. As a general rule of thumb, the cheaper the oil, the fewer additives it has and therefore, the less able it is to protect your engine.
There is one school of thought that suggests that the only difference in synthetic oils vs. petroleum oils is that the synthetics typically have a better additive package. This statement is only partially true. Synthetics almost always have superior additives than petroleum oils, hence their higher cost. However, the synthetic base stock is of paramount importance in the ability of a synthetic oil to flow at cold temperatures and withstand greater amounts of heat over significantly longer periods of time.
Petroleum base stock molecules are long carbon chains that are sensitive to stress and heat. Additionally, various paraffins that are contained in all petroleum products regardless of how well refined they are, cause oil to jell like a syrup at extremely cold temperatures. High engine temperatures and heavy loads (as typically found in towing or HARD driving) cause these chains to break down and the base stock actually boils off causing a change of viscosity and the formulation of sludge. This can happen at temperatures as low as 230º F and by 250º F many petroleum oils are suffering significant breakdown.
Synthetic oils on the other hand are made engineered specifically to provide all the lubricating properties that natural oil possesses, but none of the cold thickening or hot thinning properties of petroleum oil. Synthetics are made up of uniformly shaped molecules with shorter carbon chains which are much more resistant to heat and stress. Synthetics can withstand temperatures of 290ºF all day and still protect your engine. In fact the American Society of Testing Materials (ASTM) standard wear resistance tests are conducted at 302º F. In this test synthetic lubricants far out perform petroleum lubricants by factor of four to one (4 to 1), and greater.
Oil temperatures of 230ºF to 250ºF are not at all uncommon under extreme driving conditions. Liquid cooled cars can have extremely high oil temperatures even though the water temperature may be normal. The water temperature guage might read 210ºF while the oil temperature fluctuates between 240º F and higher,depending on how hard the vehicle is driven.
All of the manufacturers of synthetic oil tout the benefits of reduced wear, more horsepower, lower operating temperatures, and improved fuel mileage. All of these benefits are derivatives of better cold flow characteristics and higher levels of friction reducing additives that are found in synthetic oils. I can confirm better cold driving characteristics, increased fuel mileage of nearly 10%, marginally lower operating temperatures, better heat dissipation capability, and long term high temperature stability.
Are these benefits enough, however, to persuade average drivers to give up their trusted petroleum oils and pay the extra price for synthetics? Enthusiasts, yes. Average drivers, perhaps not. However, synthetic lubricants can endure extended drain intervals, which is a major consideration toward justification of the higher costs. This benefit is not widely promoted by the major oil producers most likely because they want you to pay a premium for their synthetic oils every 3000 miles just like their regular oils. Most companies don’t bother to tell you that synthetic oils are capable of going 25,000 miles or more without significant breakdown. It is not uncommon for "over the road" truckers to go several hundred thousand miles between synthetic oil changes. Reminder: The stop and go city driving that most of us do is much tougher on motor oil than over the road highway driving. FACT: City driving is considered by some raters as extreme and our vehicles need increased protection.
Fortunately, we can achieve the superior protection and the economic benefits of synthetic oils while staying within the recommendations of vehicle manufacturers.

It should be emphasized 1) That "Full Synthetic" is not the same as 100%. 2) Oil analysis is crucial to keeping the 100% synthetic lube servicable beyond what the dealer might like. If the volume is less than 14 gal. the cost of an analysis doesn't reduce your overall expenses. 3) Oil and air filters that do better than the conventional ones go along way to get that done.
