Anybody put AMSOIL in their truck??? Guy here at work recently became a sales rep and wanted to know if I'd like to try it in my new truck. Would apprecite any information about the subject.
touchy subject, and there will be as many opinions as there are facts..
Amsoil is probably superior to conventional oils.
However, in most normal vehicle (car/truck) engines, if you change your oil every 3000 miles with a normal motor oil, (Motorcraft, Havoline, Valvoline etc), these engines will last just as long as if you ran the high dollar synthetics..
I've heard that synthentics have more benefit in 'high performance' engines that run at higher tempatures, closer tolerances etc..
So, in my opinion, in normal usage the only difference between running regular oils vs synthetics is that the synthetics cost alot more.
I just received my 0W 30 oil and filter and will be introducing Amsoil to my V10 during my 2nd change at 5500 miles. This oil is recommended for all vehicles requiring 5W 30 or 10W 30 oils. It is good for 35K miles with a 6 month filter change, I also anticipate an increase in fuel mileage. As far as costs I will save approximately $20 annually, driving 25K miles. My reasons for using synthetics are fuel mileage and convenience.
I would like to caution anyone participating in this thread to read our policy about Amsoil, from our mailing list FAQ:
"Amsoil discussion by those who are dealers or have a close business relationship with dealers are not welcome on Ford Truck Enthusiasts. Amsoil dealers on the list should read Amsoil's Internet policy regarding mailing lists. Any violation of this Ford Truck Enthusiasts policy will result in immediate removal from the subscriber lists, blockage from re-subscribing and a complaint will be emailed to the Amsoil corporation. No exceptions or warnings will be given. Ford Truck Enthusiasts has been, and will continue to be, a safe harbor from MLMs."
Too many Amsoil dealers have burned this bridge by involving themselves in discussions about the products and did not reveal that they were dealers and/or agressively pitched the product. Non-dealers are welcome to discuss the products.

Just to set the record straight. I am not associated with the AMSOIL company in any way. I do not sell Amsoil or currently use any of their products. I have only done some minimal background on the subject and thought that the information provided by the truck owners who post here could prove beneficial.
I have been using synthetic motor oils including Amsoil, Mobil 1, Quaker State Ultra-Premium for many years and it has been my experience that they do perform better than conventional oils. I have heard that you should not put synthetics in a new motor as they will not allow the engine to break-in properly. They stay cleaner longer which could be an indication of less wear in the engine. Also, I run my vehicles up to 92K,165K,and 173K without any engine problems. The engines all look new inside.
I've used regular 10w-30 changed every 3k miles.. My engine in my old 89 Ranger has lasted 199k and is still going strong (sister has that truck now). I don't know what the engine looks like inside, I've never had a need to take it apart.
For every engine using synthetics thats lasted 200k miles, I bet can find 3 using normal oils. (mostly because the number of folks using normal oils far exceeds those using synthetics).
I'm not looking to start a 'oil war', but I felt it necessary to respond to the implication that a particular oil brand is the cause for allowing an engine to last 200K miles..
I am planning on switching to Amsoil for my 5sp tranny, I've heard from others it makes the shifting slightly easier..
I've ran Amsoil in the motor, transmission and rearend in my previous vehicle. I noticed an increase in mileage, don't remember how much. As an aside to that, the truck did roll easier down the road. I think that they have an axle grease too.
My '99 F-250 CC 5.4L may be getting Amsoil soon, but I won't go the the extra long oil change root.
i am running mobil synthetic in my manual transmission for first time. it has 120,000+ miles on it and it has never shifted better. i did keep the real oil i used before clean and fresh, but in cold weather it used to be real tight until warm. so, if nothing else, i am happy with the fact that it is better in cold weather with the synthetic.
I've never heard of or seen Amsoil in any parts stores around here. Why the controversy? Are they involved in MLM Multi-level Marketing? or something like that? Just curious.

I am a firm believer in the use of synthetic lubricants howeverI don't use Amsoil although I think that its a pretty good product.I use a store brand 100% synthetic 10W-30 in my truck(I won't even pitch the brand)I have a 92 F250 X Cab 4X4 that I use to tow a 7000# 5th wheel.Fully loaded,with boat on top,spare fuel,firewood,bicycles,etc,it weighs in at about 15,000#.Thats a pretty good load for the 351 that powers it.I figure it sure can't hurt to use synthetic produsts.I also use synthetic gear oil in the gearcases(again,a store brand item).One of these days I'll put synthetic in my transfer case but not until a change is due.I also use synthetic oil in my ATV.I think its best feature is its ability to get rid of heat quickly.Thats something that petroleum oil has trouble doing.
As for petroleum based oil,I've used it most of my life in cars,boats,trucks and in just about everything that has a motor.I've used it to haul trailers and to race and I've never had an oil related failure.It does the job well but I just choose to use synthetics in my truck.
I've used Castrol Syntec for years, mostly blended 50-50 to save a little money. I don't beleive in extended oil changes, but syns are supposed to "cling" to engine parts and give a better lubed start-up. That's why I have used them. Someone tell me different, and I will go back to dino at $1 a quart.
