amsoil
I was thinking of putting Amsoil and a Amsoil filter on my truck. Just wondering if anyone else has run this oil. My truck has 76000 miles on it. I use Motorcraft oil and filter now. Thanks for any feedback.

Do it. I have amsoil in my engine. The best thing I have done. I started using it after my second oil change. On cold days I would have some knocking at start up. Since the amsoil nothing....not even a peep. Even in that cold 10 below morning here in Massachusetts. The local dealer tried to have me use the amsoil filter and the flush before using amsoil. I called the local distributor and was told the flush was not needed. The amsoil is compatible with all oils. I love the fact that it states a 7500 mile oil change. I drive around 25,000 miles a year....so the less time under my truck the better.

The dealer says every 3,000 and the owners manual says 5,000....with the superior protection from the leader in synthetic oil....7500 miles is no problem. The manual states 5,000 mile service for normal driving. I have 19,000 miles on the truck. I have been using synthetics for years.....when the oil gets changed is has a slight amber color. The oil goes in just about clear. A 5,000 oil change with the motorcraft sythetic blend, the oil drains as black as midnight. I have no issues with 7,500 schedule.

Boxcar, I know the manual says 5000 miles, and Amsoil say somthing like 12,000 miles. But what would Ford say if you have and engine problem and don't have reciepts for the rest of the oil changes? I'm not arguing with your decision on the extended oil changes. I have run Valvoline 5-30 full synthetic in my V-10 since the first oil change at 2000 miles. I change it about every 5000 miles. I plan on keeping the truck for many years and hope to have a great story to tell about how many miles I got on it someday. I have an 89 Ranger 2.9L that still does not use any oil between changes. It has allway had castrol 10-40 run in it. Last year I had to change the valve cover gaskets and all of the rocker arms had thick black carbon buildup. Did not look good but not much to do about it now. The Ranger is an every day driver to work and back. I hope 15 years from now I'm still drive the SD with absolutly no mech. breakdowns. The ranger still has the original clutch, water pump, alt, etc. I don't know the millage, the speedo was unhooked for a while when it was close to the warranty expiring. Nothing broke for a year and a half so I hooked it back up.

If you follow amsoil on change interval and have a lubrication problem then you have to deal with amsoil not ford.
I've had experience on this, but in the 2 cycle world of lubrication.

I dont drive this truck every day. I dont put 12000 miles a year on it. I drive a 89 ranger ,that has 260,000 on the 2.3, back and forth to work.I have always used Havoline 10w-40 with Motorcraft filter on the Ranger. I was just wondering if this Amsoil is worth the money.I know tolerence on these new trucks is close and maybe synthetic is the way to go.

I believe that part of the reason for the 3 month interval is because that even though you don't drive 3000 miles, there can be moisture accumulation in the oil after this period of time.
And, changing the oil is cheap insurance anyway.

The 5W20 Motorcraft oil is a synthetic blend and can be had at Wally World for $1.77 a quart... I change it every 5,000 miles per the manual. I'll run this oil and change interval until the warranty is gone, then I'm switching to synthetic (most likely Mobil 1) and using a longer change interval. Synthetic does have a wider temperature range, but the warranty change interval doesn't let you take advantage of extended synthetic oil life.
OBTW, my 1992 Jeep has the 4.0L straight 6 and the manual says change the oil every 7,500 miles. I have always used dino 10W30 and it just rolled over 100,000 miles with no oil useage or oil loss between changes.

If you use any oil and Ford finds an oil related failure they will not warrant it. Why? Because it was no Fords fault your motor failed. Thing is Ford has to prove it was the oil that caused the failure and that means they did the work you need to make the oil MFG pay.
OH other that not having oil in the car or it turning to gunk from never being changed I have never heard of an oil related failure.
