Nothing wrong with it.

 

I use Motorcraft oil in my trucks and it's been fine. It is "semi-synthetic" but it is mostly conventional, like most semi-synthetics around. I consider semi-synthetics to be "conventional" for all intents and purposes, and Motorcraft is a pretty decent conventional with good detergency.

It is not really "Designed by Ford," Like their oil filters, Ford buys the oil from an OEM, a company that makes oil. Could be Shell, Mobil, Pennzoil, Valvoline, or some off brand. All you know is that it's an oil that meets their specifications and requirements and Ford puts their name on it. Ford doesn't generally put their name on junk... That oil-making company bottles it and puts into a Ford bottle with a Motorcraft logo and then Ford sells it through their dealers. They can and do change their manufacturers, so it may not be the same "Motorcraft" you had three years ago. This is standard in the auto industry. Ford doesn't make oil, oil filters, air filters, brakes, etc. The Motorcraft consumables are completely outsourced...same with every other car company.

I run 5000 mile intervals on both my trucks and have never had an issue. Always a clean motor. I use Wix filters. After 5000 miles it is still translucent and clean.

As stated above, this is just how I feel...please don't flame me. (You're right and I'm wrong...just don't flame)

 

Haha, Bobbie, I don't think anyone will "flame" you. Maybe disagree, but not "flame".

 

API tests the oil to get cerified, this is why ALL US auto manufacturers require API certified oil for warranty to remain valid.

The reason Scamsoil says to run their oil 15K miles + is to justify the high cost from the pyramid scheme, where money goes into a lot of people's pockets.

What they don't realize you change oil from getting dirty and contaminated, and it's going to get dirty and contaminated just as fast as Mobil, or any other brand oil.

 

API is just a minimum set of guidelines that most auto manufacturer's chose to adopt. After looking it up, Amsoil does offer a line of API certified oils. Amsoil's other lines don't pass API certification because the level of ZDDP exceeds the API limits. I am not endorsing Amsoil at all and have never used it, but just because they don't pass API certification doesn't make it "bad".

Yes, you should never use oil beyond the recommended oil change intervals outlined in your owner's manual. Most all oil manufacturer's push their synthetic lines by the longer oil change intervals. The reality is that this usually always goes against the recommended oil change intervals set forth by auto manufacturer's. The interesting part is that the auto industry can't agree on what those oil change intervals should be.

We can even go a step further and look at the "required" oil filters, fuels, etc. that are supposed to be used. How many people worry about the manufacturer warranty when they are buying oil, oil filters, fueling up their car, etc.? I would say not many.

 

I always say that when talking about oil. Oil is one of those sensitive subjects in the auto-enthusiast world that people are very passionate about. Most folks who are auto enthusiasts are dead-set on one oil or one type of oil...the arguments are repeated over and over, so I try to walk a fine line when it comes to oil. If I say how I feel then a lot of folks will step in and dispute it and start talking about how one oil is better and why.

Here's the skinny: No one here in an oil scientist, I'd be willing to bet. The truth is that nearly all of the claims are based upon research done by people in the oil industry and their research is rarely independent and unbiased. They hire "independent" labs to give th illusion of non-bias, but the fact is that they are paying the labs for work and they can pay those labs for whatever results they want. The API is run by the oil companies. Of course their studies will claim their more expensive product is better. There will always be claims of conventional oiled vehicles having more "build up" than synthetic. I've personally never seen that in 30+ years as a mechanic. All the "build up" I've seen has come from not changing oil...and I've seen horrible results from cars on synthetic and conventional...we're talking people who go 30k miles without an oil change, just topping off and never changing the filter...that stuff is awful

I recommend conventional to nearly all of my customers but I really don't bat an eye when one comes in wanting a particular oil, filter, or bringing both in on their own. Some people believe in their oils pretty well and it's not wise to suggest otherwise. A lot of my synthetic customers bring their own in. I have a few regulars for whom I keep various oils in stock. It's just a sensitive thing.

Anyone who comes into my shop for an oil change gets Valvoline conventional, in whatever grade their car specifies, and I use a Wix or a NAPA Gold filter (The Wix and NAPA Gold are the same filter). It's the best quality oil for the money for my operation, which I try to keep on the higher-end. I would never use anything but brand-name oil, though. And I use Motorcraft in my trucks, in spite of my Valvoline affiliation...again, it's just my preference...you guys have yours. I find the whole thing to be really humorous.

It's strictly a matter of preference with oil. I won't say anything other than use what you love to use and what makes you feel better.

 

You should ask people that have had an engine failure, while under warranty, using Scamsoil, that is not API certified, and see if they think it is BAD!

 

Even if we were there would still be disagreement and varying opinions.

I work very closely with a chemist for what I do for a living. Fuels are the main focus, but oils are touched on from time to time. It's amazing all the misinformation and myths there are out there on the subject, even within the industry. Once you get to the lay person forget it.

I agree. Find something that meets the qualities you're looking for and use it often. If you even change your oil when you are supposed to then you are a step ahead.

 

Oh, I know. There are horror stories with all products. Just saying there are two sides of the same coin.

 

Same here. I actually used the AMSoil website comparison to compare all the synthetics. For the price I don't believe AMSoil iis worth it IMO, but Mobil 1 in their comparisons is the next best thing.

 

Mobil 1 PASSED VW & Audi's sludge test, Scamsoil didn't.

 

Amsoil is a good brand.
I don't really trust mobil 1, they have high levels of iron wear - even more than most conventionals. Some believe that this is mobil 1s additive package, but i dont trust it. Why have metals as an additive pack?

motorcraft oil is hydrocracked, so its not a "blend" in the conventional sense (pun intended)

pretty much - everyone has something bad to say about everything

pennzoil causes sludge, mobil 1 has wear metals in the add pack, valvoline has a weak additive package, castrol is not a real synthetic, motorcraft is not a real blend, royal purple doesnt meet spec, havoline is cheap junk, kendall is bad, blah blah blah - long story short, all of these are good oils.
amsoil was the first in synthetics and their products are top notch. would i buy it? hell no. not for a ranger.

the reason some amsoil oils dont meet api is because they are purpose applications or applications that cost more to certify than they wwould if they didnt certify it and sell it.

all the common weights from amsoil are certified last time i checked.

the only synthetic oils i'd stay away from are Mobil 1 and any other off brand synthetic like Supertech or peak
