At the shop I work at, I have a free supply to Quaker State 5W-20. My question is, is this oil as good as Motorcraft, or should I spend a few extra dollars and get the Ford stuff? I like the fact that the Quaker State would not cost me anything, but I only want the best for my truck.

 

I'd go with the free stuff. It's oil. It'll work just fine. My dad has been running the cheapest stuff he can find in his Ranger 2.3L for 180K now, and he changes it whenever he feels like, usually 5K.

 

i used to be in that school of thinkin as far as the cheap stuff is good enough.... but i tore down the motor at 180K and ...... holy sludgy sight batman!!!! the lifter valley was very thick with sludge it had molded around the push rods. not cool. this time she will be getting mobil 1

 

quaker state and pennzoil are parafin based oils. I wouldn't touch them. The motorcraft is from ash based oil and it takes a lot less additives to get it up to spec. this means it will do the job better and longer than quaker state. Your truck.. do what you want. Just my 2 pennies

 

Thanks a lot guys. I will stick with the Motorcraft. It's only $13 all together from Wally World anyway.

 

paraffin based oil has nothing to do with paraffin wax. paraffins are a class
of organic chemicals , just like ketones are a class or family or organic chemicals

what are ash based oils? what is the source of your disinformation?

Keep records of using Quaker State and you get 250,000 mile 10 year lube coverage. Stuff can't be that bad!!

 

Quaker State is totally fine, no different than Pennzoil, Valvoline etc in my opinion. Oil is oil, and free is free. Some people swear by one or another, but really the important part is when you change it. Save the money for that expensive liquid called gas.

 

i was always told that pennzoil was recycled ??

 

I agree. I've always ran QS in my vehicles and never had a problem. I've never tore down any of the motors because I've sold them with high mileage or for the farm trucks they just kept going and going. Free is free, use that money to buy something else.

 

I have heard about people's engines being crapped up because of that brand. But who cares what the inside of your engine looks like? Is Martha Stuart gonna inspect it?

RUN THE FREE STUFF!!!

 

Your just a fine specimen huh? why the insulting tone? I guess your the one with the most disinformation:

I learned about the quality of the two different types years ago in the Air Force. Plus experiance with pariffn based oils in auto engines in the 1970's showed me nothing but sludge build up. Some times so much so there was enough room in the valve covers for the rocker arms to move but that was all. I am sure it is better now with new oil technology, but I still won't use it. I think it would be good for you to loose your tone and do some research of your own.

 

Chris, sludge is no more caused by paraffinics or crude parafins than dirty toilet seats cause babies. Oils from the 70's contained the new wonder component called polymers. Polymers were the agent that let an oil be a multiviscosity. The early polymers were notorious about sludging an engine. Ask any GM owner that used the speced 10w-40. Here is a dictionary that is provided by Noria. Noria is at the top of the game when it comes to teaching about lubes and the components.
