Actually, they do not have to honor the warranty if you do not use the specified oil and they can show that the damage was caused by using the incorrect oil.

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

First of all, there is nothing wrong with the Fram filters. I had a '90, '91 and 92 5.0's and all used the Frams. '90 and '91 sold with 33k on them. The '92 had 168k on it and all hard miles. A lot of racing on a stock motor. However, I did use Mobil 1.
I ran a '98 Accord for 160k+ miles and I currently, still have a '95 4x4 Blazer with 172k miles on it.

The Mach uses the Motorcraft filters because I have heard the construction is better AND I am racing in it as well as using it as a DD. If you're using it as a DD and not racing it, Fram would be just fine in my opinion.

But when in doubt, use factory filters or write to Ford and get it in writing as to other manufacturer's filters.

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

I have seen evidence that the Fram filters can self destruct on the inside. Another problem is the anti-drain back valve is glued in place. After testing the flow on a Fram filter, I was lead to believe the cold oil does not get filtered until the oil has warmed up, filter went into bypass. The input pressure was 40 psi and coming out of the filter, with cold oil was 37 PSI. As the oil warmed, the output pressure dropped into the low 30's, like it was getting filtered, no longer in bypass. This PSI was comparable to other filters in the test, but only after the oil heated up. I believe the oil temp was in the 40's before the test begun.
I don't like the idea of dirty oil pumping through my engine or a glued in place anti-drain back valve. Fram in the past, built their own filters. I hear they are built by another company now, and cheap at that.

You are correct that if they can prove the damage was caused by the oil you used they do not have to honor the warrantee.
They may balk and probably will, but if it is an API certified oil there is nothing they can do. Unless you are using something real funky and there is obvious abuse. Use something that meets or exceeds their recommended viscosity range.
Most of them do not know the laws, or do and try to blow smoke up your butt.
A good service writer/manger is worth their weight in gold.

I had a service writer tell me that my warranty would be void on my F250 if I did not get all the maintenance done there. I asked him if he would care to repeat that in front of the manager, he said "oh that starts next year". So I asked him he wanted to repeat that in front of the manager. I have not been back.

Guys....There are several Fram filters, from the low ball absolute cheapest $3.00 model to a hi quality long life $10.00 one. Which one are you referring to? I imagime Fram knows how to make a quality filter, but maybe they don't in the price leader market.

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

Sure it's about economy. That's where the pressure came from to develop better oils. Why not use the lightest oil possible if it does the job. I'm yet to read about a normal use oil failure from using a 5W oil (or 0W for that matter) on any web sites in any climate. And there are lots of advantages to 5w and 0W oils....from cooler running engines, cleaner running engines, faster oil pressure for less wear on startup to yes....better fuel economy.

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

Haha!! 0W20 is back. :wow:

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

5w30 may not be anyproblem at all, on my escorts the 2000 says to use 5w30, the 2001 says 5w20....exact same motor.

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

This may help some of you. The major difference between conventional motor oil and synthetic oil is the refining process that synthetic oil goes through. Conventional motor oil has different size molecules that make up the consistency of the oil. i.e. 5w30. Where as synthetic oil is refined so that all of the molecules are the same size. Basically filtering out all of the smaller and larger molecules.

If ford recommends 5w20 then that is what you should run. I have read some of you are using 0w20. You can do whatever you want w/ your Mach 1, but personally I definitively wouldn't recommend 0w20. I think water might be thicker than 0w20, and probably a better choice. You may be getting better gas mileage w/ 0w20, but i would rather have my car last longer than get one more mile to the gallon.

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

there are Cobra guys that have ran 0w-30 since 1999 and have no problems at all....I have NEVER heard of a 0w20 or 0w30 oil causing a problem.

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

The original reason for using a low viscosity spread oil:
With dino based oils, as others have mentioned, you start with a lighter weight base oil. To achieve a multigrade oil, you need to add VII's (Viscosity Index Improvers). These VII's are long-chained polymers. When cold they bunch up, when hot they extend, but only to a limit, and by doing so, they limit how much the viscosity decreases.

The reason to use a low viscosity spread for DINO oil, is because the lower the viscosity spread, the lower the amount of VII's needed. The reason folks used to recommend things like 15w40 is because some companies could make dino 15w40 oils that used little to no VII's.

Why are VII's bad? Simple. They work because they are molecular long chained polymers that depend on their restricted uncoiling to work. Unfortunately, these VII's can chemically break down AND the molecules can literally be sheared mechanically/physically. Once physical/chemical shear has happened, the oil will have a permanently lower hot viscosity (which tends to mean less protection).

This is also one of the reasons the old fogies (like me) would use 20w50 oils; one was for for the lower viscosity spread. BTW, I'm skeptical of anyone who tells you something like "keep the spread to 25 or lower". It's not the difference from subtracting the numbers. It's the difference from dividing them. When folks don't understand this and STILL want to give advice, you need to question their understanding of tribology. A 20w50 has a 2.5X spread. Any VII's needed only need to account for a 2.5X difference. A 5w30 on the other hand only has a 25 weight numerical spread compared to the 20w50's 30 numerical spread, BUT the 5w30 needs VII's to maintain a 6X spread. You can do the math for other weights.

Suffice it to say, some synthetics are capable of 10w40 without VII's (Red Line is one), and NO synthetic can currently be formulated for 0w40 without a decent amount of (too much IMO) VII's. Mobil1 0w40 sheared like crazy in just 1500 miles in my car and that didn't include any track time.

The other reason for old schoolers running 20w50; the base viscosity is higher, so when (dino 20w50's usually still have some VII's) the oil shears, you still have a higher base weight (meaning at the absolute worst, a dino 20w50 won't shear below a 20 weight).

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

Now the real reason 0w20 was even made in the 1st place.:soapbox:

Made for most all HYBRED cars Toyota ,Honda the 2 largest manufactures to increase mileage. The oil is more like sewing machine oil to lessen the internal drag for an engine only used Part Time . The oil was /is also more expensive to make since it is refined to a higher standard. Several oil companies refused to even produce it ,so the ones that did charged what ever the market would stand. Racers picked up this low weight oil to lower track times,not for the e longer service . They could do this since engine piston to wall clearance (002-004)was reduced by better metal and engine seals because of emissions.
However as more people drove their HYBRED cars on the hi -way demand increased.The old change the oil sooner plan came up again ,3,000 instead of 5,000 or 7,000. This increased the cost of driving more and people complained of the high cost of the oil to the dealers. I was required to have a special class on them while working for Toyota and later again for Ford as a Tech. This was mostly for the high voltages that the cars use while in the electric mode,250-300volts .The old saying that its not the product ..its how you use it ..comes into play here. Ford has changed its mind so much over the years that if i serviced any Ford i had to look up the oil it used 1st..:crazy:

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

Very true..Quaker State did this earlier, S:crazy: aid they will pay for engine damage CAUSED by their motor oil being used. Several people found out that in court it was almost impossiable to prove it .So much so that they never lost a case !

I use amsoil 0-30 I used mobile 1 for about 3 oil changes when I used amsoil I felt the engine smoother

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

Fram filters = junk in a can your paying for there hudge advertiseing. In worked at a parts house and we cut all the major filter apart and fram had the least. Wix and Motorcraft are good and Mobil 1 filters.


LS:claus:

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

I thought Wix made oil filters for a bunch of different companys? Don't ask me which one's (LOL).

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

Wix does make for other branded filter NAPA being one of them many filter are made under other names.... Just remember most meet or exceed O E spec ,,,,,,,,,,,, Just got to read befor You buy :wow:

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

ummm. they are still selling 0w-20. Did I miss a thread about them bringing it back for a specific reason?

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

They were still sellng it 5 years ago when this thread was started. :OUCH:

i been using 5-20 castrol syntec for about 2000 miles'' car has 90,000 on her''would it be ok to switch to 5-20 mobile one or stay with the syntec

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

i work at napa and we still sell 0w20 mobil 1!

Re: Important Information About Mobile 1 Synthetic Motor Oil For Mach 1's
 

I use 5-20 conventional Oil like quak er state and change it 3000 miles.
Does that make me a bad person or just cheap?
