Any amsoil dealers on here or f150 users who can verify these are the correct p/n's for my 2007 f15 fx4? Some of the fluids have 'options' on the Amsoil site, so I'm not 100% sure. Not sure if severe gear is the normal recommended for the rear diff but the other option only comes in 5gallon containers??

amsoil engine oil filter EAO11-EA (25,000MILES) $17.30

amsoil (wix) 4R75W transmission filter. p/n 58955-EA $25.00 USD

amsoil 5w20 XL sythn motor oil 7500mile change oil - XLMQT-EA $6.80USD

amsoil synthetic universal transmission fluid p/n ATFQT-EA $9.75 USD

Front diff - sae 80w-90 synth - AGLZT-EA $9.20 EACH

rear diff -75W140 FOR LSD SEVERE GEAR SVOQT-EA $15/quart

thanks!

Wow, nice job of doing your homework.

Do you know which of those fluids in an 04-08 f150 are not synthetic from the factory.

 

anyone?

Is that what you guys are using for the diffs? or since it looks like 75w140 severe gear in the back I should just use 75w90 severe gear in the front? I don't do much towing, a couple snowmobiles in winter and the odd 3000lb car with a 18ft car hauler (short distances, less than 100 miles). A couple times a year also haul small fishing boat and tent trailer.

Also, on the limited slip rear, amsoil has a note " Models W/ Traction-Lok Rear Axle Add 4 oz of friction modifier part no. C8AZ-19B546A (EST-M2C118-A) or equivalent) ".

I assume this means all limited slips need the modifier, like my 2007 5.4 fx4 with 3.73 gears and trailer package. I'm guessing since its the same oil for non-limited slip, the answer is YES

 

I like your list.

I'm using the AMSOIL 100% Synthetic 0W-20 Motor Oil (ASM) instead of the SAE 5W-20 XL Synthetic Motor Oil you listed.

I've used it in the last two oil/filter changes and am content.

 

I use Amsoil 5w30 high performance and a Motorcraft filter. 1 yr drain, new filter every 3 months. Been thinking of changing to the 0w20 next time.

I went Motorcraft on the rear diff, couldn't get a straight answer about the friction modifier. Some say all you need is the Amsoil, others say you must add the fm no matter what oil. Since I had to go to Ford for the fm I just got it all at one place.

 

You drain the oil annually and change the oil filter every three months, correct? Cool.

But how do you change the oil filter only with a pan full of 7 quarts of oil without making a mess?

Go the AMSOIL 100% Synthetic 0W-20 Motor Oil (ASM) nxt time... you'll be glad you did so.

 

I run the AMSOIL 100% Synthetic 0W-20 Motor Oil with the AMSOIL filter and change them both one time a year, so far it works very well.

 

When you pull the filter it's just the oil in the filter you lose, nothing different than when you drain the oil then pull the filter. I then fill the new filter and install.

 

Why is the 0-20 better than 5-20 ?
Just curious

 

Wow! I never knew that.

 

It's not really a matter of "better." I'll let the astute folks at Amsoil answer and address this -

Question: My owners manual specifies 5W-20 or 0W-20 oil. Do I really need to use 5W-20 or 0W-20 oil and why did my 2000 model year vehicle require a 5W-30 oil, while the exact same engine in my 2001, 2002 and newer engines "requires" a 5W-20 or 0W-20 oil?

Answer: NO! You do not need to use a 5W-20 or 0W-20 oil. Do not let your dealer scare you by telling you that you have to use 5W-20 oil for your warranty. That is a tactic that some dealerships use to scare customers. 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 fluids you want to use.

The main reason 5W-20 or 0W-20 oil 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. For model year 2001, the change to a 5W-20 oil will allow Honda and Ford's overall CAFE to increase by a very small amount, typically in the tenths of a mile per gallon range. 5W-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.

Question: Could using a 5W-30, 10W-30, 0W-30 or even a 10W-40 or 20W-50, oil in my vehicle which specifies a 5W-20 oil void my new car warranty?

Answer: 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 5W-20, 5W-30, 10W-30, 0W-30, 10W-40 or 20W-50 (for racing and high performance applications in, for example, a Cobra R Mustang) 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 motor oil and or/ a specific brand of 5W-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.
