If so, which oil are you using, for how long and what are your thoughts/impressions?
Also what motor do you have.

I don't use 20wt oil Darryl. I use 10 W 30 like
the manual says to use for my 4.7.
When I did work for the Ohio Turnpike many years
ago, all our fleet trucks did use 20wt oil only.
I never could figure out why but I also must add,
I never lost an engine either.
Why do you ask anyway?

I tried Castrol GTX 5w-20 for 200 miles doing a engine flush. The throttle response was WAY better than with the Royal Purple 10w-30 I had been using.
Seeing as Ford & Honda spec this weight, I was just a little curious. It just looks so damn thin!
I have now settled on Mobil 1 0w-30 and have about 1,200 miles on it and it seems to be in the middle of the 5w-20 & 10w-30 in terms of engine response and MPG. There is also ZERO noise at cold start up with the Mobil 1 (unlike the Royal Purple).
So in a nut shell, I'm just hoping someone else would make the change before me!

| Amsoil and 20wt or 20w oil - viscosity definition
IP: Logged
Message:
First let me offer viscosity information.
After breakfast I will be back to discuss 20w oils.
__________________________________________________
VISCOSITY ... in the general term is defined as " a fluids resistance to flow". It is a measure of the internal friction of the fluid or the resistance to the movement of one layer of molecules relative to an adjacent layer.
THE LOWER (SMALLER or FIRST #, as in "10w-_) NUMBER ... is the Cold Cranking measurement, made at low temperatures, using a concentric cylinder viscometer to predict the oils cranking resistance in an engine during cold starting.
The measuring devices, or viscosmeters, most often used are in the form of close-fitting concentric cylinders. The fluid being evaluated is placed between the cylinder walls, the outer cylinder is held stationary and the inner cylinder is rotated. The speed of rotation is measured for a given force to calculate the viscosity, most commonly reported in cp or centipoise units. Also known as Absolute Viscosity.
THE HIGHER (BIGGER or SECOND #, as in "-30") NUMBER ... is commonly measured in capilary tubes, in which the time for a fixed volume of fluid to flow through the tube under gravity at operating temp (100c)is measured and reported as cSt or centistokes. This is used most commonly to report the normal operating viscosity of motor oils or the higher number.
--------------------------------------------------
" __W- " is a viscosity GRADE, not a viscosity MEASUREMENT.
When testing for cold fluidity, the temperature is lowered approximately 5 degrees centigrade between each test.
The Cold Crank Simulator Apparent Viscosity is tested at:
-20 C for 10W-
-25 C fpr 5W-
-30 C for 0W-
It is my understanding that the oil has to be labelled at the lowest temperature it meets the specifications.
It may not be long before someone comes out with a " -5W-30 " which would correspond with -35 C.

| Amsoil Series XL7500 Synthetic Oil 5w-20
IP: Logged
Message:
I hear many consumers thinking of switching to a "Xw-20" motor oil --- seeking higher MPG using a thinner oil. Keep reading --- and BE CAREFUL!
I would only use "Xw-20" if the Owners Manual called for it --- not simply to try to increase MPG in a vehicle calling for a heavier viscosity.
__________________________________________________
I recall when consumers were worried about 5w-30 oils when they were first recommended 10+ years ago as replacements for "straight weight oils". Now consumers are worried about "Xw-20" oils.
It has been my same experience with Synthetic Oils. First it was "it will ruin the seals", then it was "it will ruin the engine", now they say "it costs to much". Always the worry warts or the flammers around to add negative comments without first seeking knowledge.
Too many people like my grandfather --- that just won't change his old ways and learned habits --- and open his mind to something new.
--------------------------------------------------
"Xw-20" oils have been "reintroduced" so that automobile manufacturers can increase gas mileage and meet CAFE requirements (by using a lower viscosity, or thinner oils. dont forget emmissions and the little EPA stickers.
Note: Observing used oil analysis reports --- the bearing wear rate --- as well as the lead --- using a "Xw-20" --- was higher (in the same test vehicle) than when it was using "Xw-30". I would be very cautious about going too thin.
Repeat: I would only use "Xw-20" if the Owners Manual called for it --- not simply to try to increase MPG in a vehicle calling for a heavier viscosity.
--------------------------------------------------
I think that "Xw-20" performs well in most engines that recommend "Xw-20" and some that recommend "Xw-30", --- and does NOT perform well in some situations. You (as the consumer) have to be careful and make the appropriate decision and take the proper precautions.
Again (and I can-t say it enough) --- I would only use "Xw-20" if the Owners Manual called for it --- not simply to try to increase MPG in a vehicle calling for a heavier viscosity.
-------------------
The "thick vs. thin" viscosity debate. The answer is --- it depends on your engine. The whole arguement is meeting CAFE requirements and EPA standards. Heck --- Mobil1 "Xw-30" and many others --- thin to a "Xw-20" after a short period of use.
--------------------------------------------------
Amsoil has spoken out against using "Xw-20" oils in vehicles that don't require it.
I personally don't like "Xw-20"'s. I am certain that most automobiles that recommend the thinner oil will have no problems with it, --- but the same cars could be better protected using a good synthetic "Xw-30".
--------------------------------------------------
The specs on Amsoil Series XL7500 oils (for the record --- a Group III), are actually a bit better than their original SJ formulations, but as I stated before --- Amsoil's 5w-20 is probably too thin to be used in 5w-30 applications.
Amsoil Synthetic XL-7500 Motor Oils
AMSOIL XL-7500 Synthetic Motor Oils are specially formulated to provide outstanding wear protection, power, fuel economy and performance for 7,500 miles or six months of service. With AMSOIL XL-7500 Synthetic Motor Oils, motorists driving 15,000 miles a year need only change their oil twice annually. AMSOIL XL-7500 Synthetic Motor Oils offer a high degree of convenience and savings through their ability to perform and protect engines for extended periods.

From what I have read AMSOIL introduced their 5w-20 weight oils for the sole purpose of not losing Ford and Honda customers who feel that they must use exactly what the owners manual recommends as far as viscosity goes.
Most Honda tuners that I know will not use anything less than a 10w-40 for street and strip and nothing less than 5w-30 for stock engines.

I just gave up on my wife using 5w-20.
You do not need to use a 5w20 oil.
The only reason 5w20 was specified 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 manufacturer's 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, and still meet mandated CAFE requirements, they must also sell smaller cars which have much better fuel economy ratings to offset the poor fuel economy ratings of the larger vehicles.
5w20 oil is a lighter viscosity than a 5w30 oil and therefore has less internal engine frictional losses, or less drag on the crankshaft, pistons and valve-train. This decrease in frictional power loss promotes increased fuel economy. This increased fuel economy is virtually undetectable to the average consumer without the use of specialized engine monitoring and testing equipment when compared to a 5w30, 10w30 or a 0w30 viscosity motor oil.

Oh yeah. Here is why I gave up on 5w20.
5w20 oil has less film and shear strength than a 5w30, 10w30 or a 0w30 motor oil. This can lead to increased engine wear under today's demanding heat and high-stress engine performance conditions.

OK, there is an Oxy-moron here. If 0w-20 causes increased engine wear there must be more friction. More friction will reduce fuel economy. Does that not make sense? If it increases fuel economy it must be reducing friction.If it reduces friction, how could it cause increased engine wear? Does that not make sense? Something just isn't adding up here.
Also, my owners manual calls for 5W-30 on the 4.7L not the 10W-30 RadioMan referenced. My 3.9L also called for 5W-30.

Ok, here's another question to Stephen. I've been using Amsoil 5w-30 in my 4.7. A friend recommended using the Series 2000 0w-30. First question, can I use that in the 4.7? Second, what are the pros/cons of the Series 2000 0w-30 compared to the standard 5w-30?

Whiplash,
I would not run 0w-20 in a vehicle that did not require 0w-20. The engines that run 0w-20 are designed for that particular oil to assist automakers in acheiving CAFE requirements. I may come back and post more on this topic later.
__________________________________________________
Andrew,
Hopefully, I can discuss various oils without adding to the confusion.
IMHO, Amsoil's best oils are their Amsoil SAE 5w-30 (Product Code ASL) and Amsoil SAE 10w-30 synthetic motor oils (Product Code ATM).
Amsoil Series 2000 Synthetic Motor Oil's strong points are fuel efficiency and temperature reductions. Amsoil Series 2000 uses racing technology ( base & additives ), but it is designed for street vehicles.
(Note: If anyone has a small 4 or 6 cylinder -- you will get the most hp out of the 0w-30. Large V-8's don't do as well with the 0w-30).
I know the Series 2000 costs more, but it is probably my best selling oil. The price difference between the SAE 5w-30 and 10w-30 vs. the Series 2000 is $2 per quart, but only about $12.00 per year. This is using a five quart estimate for the inital change and one quart added after the filter change at six months.
Benefits of Amsoil Series 2000 0w-30:
- Due to higher detergency, it provides better engine cleanliness
- Provides a fuel savings of approx 2% - 3% in comparison to the SAE 10w-30 in short trip driving conditions.
- It holds up slightly better than the 5w-30 over long drain intervals, particularly with regards to TBN retention.
- Better cold weather performance than the 5w-30 or 10w-30. If you have read my "VISCOSITY" thread you will understand why. (Since Summer is upon us I mentioned this last. Otherwise, during the Winter it would be listed first)
Many Amsoil customers are extending their drains to between 12k and 15k miles with the Amsoil Series 2000 -- which is per Amsoil's recommendations of 2 - 3 times manufacturers recommendations(without the need of oil analysis).
__________________________________________________
You want to talk GREAT OIL !!!
Amsoil Series 3000 -- Fuel efficient formula for both gasoline and diesel fleets. Contains the beefiest additive package of all AMSOIL Motor Oils, with a Pour Point of -60°F a Flash Point of 457°F, and a TBN of >12.
__________  __________
Amsoil Series 3000 is quite possibly the best long drain synthetic oil on the market. Amsoil Series 3000 is more shear stable and it will hold up better in drain intervals beyond 12,000 miles. Less oxidation/nitration and better TBN retention.
