You have joggle my old farts memory.... we get a lot of 6.0 and 6.4 diesel
engines through our shop (no surprise since we ARE a Ford dealer) that have
had aftermarket oil filters installed. Jiffy Lube will happily dispose of
your old filter cap since the aftermarket filter comes with it's own (ill
fitting, leaking) cap.
Here in Canada, that new oil filter cap (the one that will cure your oil
leak) is about $90 CAD (not including the price of the new oil filter).
Choosing a mechanic is like choosing a doctor... find one that you can
easily get along with... find one that is brutally honest... Be aware that
he may make the odd mistake and he will fix that mistake without hesitation.
Many of my customers have been coming to me for 30 years or more....
Quicky oil changes by inexperienced minimum wage earners shouldn't be a
viable option in anyones playbook... FWIW - I am paranoid to the point that
I'm reluctant to eat in a fast food joint where I can't watch my meal from
beginning to end... (Did anyone see that Gordon Ramsay show where the fast
food guy picked a piece of food up off the floor and tossed it back in the
deep frier? Yummmmm!!!)
That's the rub. It comes out of a tank. Neither you, nor the service
station who uses it, KNOWS for sure what brand the oil REALLY is -
except for the lube shops that are owned by a particular oil company.
And then you don't know for sure what line of oil they are actually
using. Every oil company has their "economy grade" and their
"premium" at the very least.
I know for a FACT that sometimes when you order (as a garage) a
certain brand of premium multigrade oil from a distributor you do NOT
get either that brand or their premium oil.
When you use packaged oil you KNOW what you are getting.
I'm NOT saying that bulk oil is in any way necessarily inferior - I
used to use bulk oil a LOT in my service station and dealership days.
I generally bought only directly from the oil company - when at the
service station from the oil company that owned the fuel tanks -
Texaco , Shell ,, Esso, etc, and at the dealerships from the single
line distributor for either Castrol, Quaker State, Kendall, etc or the
oil companies listed above.
When the dealership started buying from a large industrial lubricant
company that distributed Quaker State, Valvoline, Castrol, and several
other lines we never knew for sure what was in the tank. Can you say
"brand of the week"?
The only way to know what oil you were REALLY getting was to order
Kendall GT-1 - none of the "competitors'" oils were that distinctive
Well, at least you think you do. Further, when you get expensive oil out
of a bottle, who knows if that is really what you're buying,
partilcularly at a place where you're not the one opening the bottle.
At our company's fleet garage, we bought "bulk" oil, but it came
packaged in 55 gallon drums. It was never delivered in a tank truck
and pumped into an open bulk tank.
This level of "bulk" was substantially cheaper than buying bottled oil,
and the risk of contamination was less.
I used a lot of "barrel" oil for many years from the multi-line
distributor, but then they decided they didn't want to handle barrels
anymore at they put in bulk tanks with metered pumps - made it a lot
wasier than pumping from a barrel into a pouring can - no more funnels
required - and less, not more, possibility of contamination because
there were no extra containers or stages of handling involved.
The only problem is you NEVER really knew what you were getting. They
handled Valvoline, Castrol, Quaker State, and at least 2 other brands
- all of which made good oils - and also cheap oils. Which grade
were we getting this month? from which company?.
The article linked above is also a helpful read. I noticed the part
that says "Depending on driving conditions, we expect oil change
intervals could be approximately:
Up to 10,000 miles Normal commuting with highway driving
5000 to 7500 miles Trailer tow/high load driving
3000 to 5000 miles Short trip usage, extreme cold or hot
The fact that two very different different car manufacturers (Honda
and Ford) are saying a 10k mile interval is fine for many speaks
And that encompasses what - about 90%? of all oil changes in North
And with short trips in cold weather a synthetic oil does not buy you
much in extended oil life. SOME, yes. But not a lot. In high
temperature (extreme heat) synthetic DOES buy you a fair return in
extended oil life.
"End of story" is a good epitaph for this rather useless thread. This
subject has been argued on this and other newsgroups for years.
You take the point that some are foolish because they dont subscribe
to your ideas about lubricants, maintenance intervals, etc.
You havent proved any points. You just keep talking, saying the
same old things, never with an iota of data.
It is boring.
