so, do you know much about cars? do you know about 3 vs. 5 bearing
crankshafts? do you know about cast cranks vs. forged? do you know
about high silica brake pads? transmission clutch pack quality? how
about tolerances? suv rollover? solid rear axles straight out of the
20's? leaf springs? red rear turn signals to save 2 bulbs and a few
yards of wire? dude, no kidding, there's not a single nut, bolt, strand
of wire, or even paint particle on a ford that is not the cheapest they
think they can get away with. not one single thing.
No, jim, I do not know much about cars.
Why do you ask? Your question has no bearing on the
issue at hand.
The issue is substituting 5W-20 for 10W-30.
Do you have anything useful to add?
And, jim, I do keep my mouth shut on matters I do not
understand. How about you?
Here we go again. When you have nothing useful to say
about the sugject at hand you talk about something else.
You do this frequently. Jim, you don't have to post;
Ford did the right thing, they published, according to
John, which of their older models can savely be switched
to 5W-20. But you call them idiots.
ford also published that it's ok to leave the brake fluid for the life
of the vehicle. is that ok just because ford say so? nhtsa don't seem
to think so.
the point is karl, since you seem to be /so/ interested, that ford
quality is poor. the slightest problem with a 5w-20 oil in a poor, low
tolerance, minimal material quality ford motor /will/ result in a
shortened engine lifespan. and ford say that's "ok", using the same
[economic] rationale that justifies not changing the brake fluid, i.e.,
it's out of warranty and the consumer pays. if that's ok with you, good
luck to you.
You bring up an interesting point regarding the use of "lighter" engine
oils as relates to mileage goals.
The question in my mind is, "Are the current materials used in engine
internal parts such as pistons, valves, crankshafts, engine blocks,
camshafts etc. substantially the same as say an early 1980's Honda?"
My 2001 owners manual says "5W-20 oil is formulated for year-round
protection of your Honda, to
improve cold weather starting, and
to help your engine use less fuel".
Is Honda only concerned about cold weather? What about extreme hot weather?
Does a 5W-20, 5W-30 or 5W-40 not have the same cold weather protection?
I would prefer hot weather protection also.
I think the main reason for recommending this oil is as stated to "use LESS
