I don't read that implication at all. It basically states that 5w-20 is recommended for best fuel economy. It's outright expressed that you can deviate at fuel economy's expense if you feel so inclined.

Not all things have a polarized "180° out" congruency to them ...at least in effect.

Edit: But since we're giving tribute to Mobil 1's rhetoric on such matters ....

What was it in 1974 when someone who had a 10w-40 or 10w30 spec'd for their engine?? At that time, they only had a 5w-20 for the entire NA automotive market.


You are probably right. I do not think the engine will have any problems either way. Those 6.8's are very common in motor homes. I wonder if 5W20 is still spec'd in those?

Well, it was. I don't know if it's still in the archives, but a member, Cathy (K?) Covington had a V10 have bearing issues and she was late on her oil change on the motor home. Now I really didn't have too much sympathy for the hassle Ford put her through. They were doing some racing circuit towing motor cycles. The limited description of their lifestyle didn't indicate that $7000 was going to be a hardship and could have been written off to nature's way of saying you make too much money..

..but that said, she had to go through a lot of hassle and finally got a new engine for (iirc) $2000. This was an agreed concession on both party's part to avoid a legal hassle where she probably would have been a triumphant loser $-wise.


..but back to Mobil 1 ..you could have commented that they abandoned 5w-20 for a number of years after a few too many engines didn't agree with it and failed. I don't believe it returned for over a decade ..maybe longer.

Yes it is. Grandparents have used MC 5w20 in their 2001 29ft Winnie with 40k since new. No oil usage and runs like a top. They pull a toad on occasion.
 
I can fully appreciate the fact that someone is willing to share some invaluable, real world knowledge or wisdom that I may lack. However, I can indeed be perplexed as to why these people's information is not received with a bit of apprehension or confusion. I say this because spelling and grammar are an indication of mental capacity/faculties. Spell-check is FREE and readily available on any word processing platform with a simple right-click. I'm simply calling that out.

I know of some old-timers that prove that statement inaccurate.
 
Spelling is easier due to the checkers ..it's not perfect, but Google will usually find the right spelling for you.

Grammar, otoh, has to be formatted. Most of us found it as interesting as cereal without milk. It was somewhat easier to learn Spanish (no, I didn't really learn it) simply due to the format.

The more socialized here did not learn it out of desire. They learned it out of necessity. Their collegian career mandated it. They may have even found it interesting ..although I can't imagine what social issues someone like that would have in interpersonal success in relating to others. I'll accept someone saying "It's just what you do. You learn it as good as you can." ..but "interesting"? Not a chance. I'd say that it was tolerated and mastered for ulterior motives beyond the subject itself.


We all have our hierarchy of needs. Grammar may be lower on some people's list than others.

Yes, and let's not forget Dr. Haas's Maybach, with its 600 HP V12, where he's been using 5w20 or 0w20 in it since new. His UOAs are consistently good.

Also, let's not forget my 300M which spec'd 10w30 where I used 5w20 for the last 3 years that I had it. I've posted numerous UOAs on here and 5w20 turned in the best numbers of the various viscosities I tried over the years.
 
Hey,
why all this concern about the lack of protection with the 5w20 oil?

How many time this is the recommendation for the Ford vehicles? If this oil really have any problem about wearing, would be a tons of models stopping because engine failures.
 
If you will notice this thread is not about 5-20 being able to lube your engine well, but will heavier oils protect Ford engines as well as the lighter fluids. Many here on BITOG prefer something heavier than 5-20, myself included.Mobil tech seems to be saying it's OK to use the heavier fluids, but there may be a slight mpg offset. As I stated at the beginning of this thread Mobil tech told me 5-30 will be fine for my Fords but may lose 2-3 tenths of a gallon on mpg.
 
This "oil protection" banter is ridiculous and neurotic.

5w20 works perfectly fine in any engine made for it. it will protect just as fine and no one here raceses their ford focus to work.

Saying that 0w40 will offer more protection is also ridiculous. Most wear happens during startup and the faster the oil flows, the lower the overall wear.

It is ok, to use a heavier oil, but it is not BETTER.

This neurotic conjecture and pure all out [censored] has to stop.
 
Interesting fuel economy comment from Mobil-wonder what they'd say about their AFE 0W40-you would think that the improved cold flow would counteract some of the warm flow losses??

Welcome to the site. You have much to learn...


In many applications, what he has stated is true though. This is why many euro manufacturers specify a minimum HTHS value. And the reason Ford specs 5w50 for the Ford GT and GT500, both of which have Modular engines, which, in normal applications, specify 5w20.
