HELP!!! Adding Mobil 1 to different synthetic
Hey,
Taking a road trip tommorow in te truck I bought a few months back.
The guy was using Amsoil synthetic 10W and I just got gas and checked
the level......LOW You can't buy Amsoil at the store. Can I add Mobil 1 instead
until I can order Amosoil on the internet. Someone once told me if you change some oils or mix them the oil can turn to peanut butter. Any advice would be great!

Way too much has been made of "addititve clash". I had an auto shop teacher who said that the marker dyes in different brands would interact and form abrasive sand deposits! Dont worry too much about it. Modern oils will mix without any problem. Since Amsoil is primarily PAO, if you use RP or M1 you will at least stay mostly PAO.
Another thing people fret too much about is oil level. Unless your engine consumes an abnormal amount, there is no reason to keep topping it up. A quart low does zero harm. The distance between the full and add marks on my Toyota is 1.5. Carmakers test at extreme angles to make sure that the oil pickup is not sucking air at or below the add line. On a Lycoming aircraft engine there are marks at one and two quarts. It is recommended to leave it a quart low, unless setting out on a long trip. Understand that "normal" aircraft oil consumption is many times higher than for a car or truck.

Part of the certification for oils is being compatible with all the other oils, so it shouldn't be a problem in general. Most of AMSOIL's line is uncertified so there's no guaruntee in this particular instance, but I wouldn't worry at all if it was my truck.
BTW, if your truck is consuming more than a little oil it really doesn't make sense to spend the money to stay with AMSOIL IMNSHO.

If in doubt, call the mnufacturers & ask if it's ok to mix the two.
Seeing as how our engines are also cooled by our oil, don't know that I'd want to take the trip with it 1 qt low, as that would mean the remaining oil would have to bear the extra heat & lube load & with you running on the road in hot weather, there will be more oil in the to end of the engine & less in the sump, because it takes a while for the oil to drain back down to the oil pan!!!!
Also with it using oil at a unknown rate, you could run lower than is tolerable & maybe cause something to come unraveled, all for the cost of an oil change.
If neither recommend you mix the two, then change it, take extra with you & keep a check on the level during the trip,so you can get an idea of the use rate.
Just some more thoughts to ponder.

No matter how much oil you have, once it all gets up to temperature, its not going to cool the parts any more or less. Aircraft are far more dependent on oil for cooling than our trucks, and they do not recommend running topped off all the time. I am not aware of a Ford light truck with external engine oil coolers as factory equipment, however, my Chebby with tow package did have one.

You also might want to replace your PCV Valve with the correct Motorcraft Part. Sometimes they get gummed up, and are not efficient anymore. Well worth the price (cheap) and very easy to replace.
I like to replace my radiator cap and PCV valve every five years, whether I think it needs one or not. Never any problems.
