Your Business Go "Up the Tube"
7 Questions for Dan Widmar
Reprinted from moderncarcare.com
Dan Widmar is the president of Fluid Evacuators
Inc. in Mesa, AZ. His is among several companies that manufacturer
equipment that uses vacuum presssure to extract air and fluids
from automotive systems like transmissions, brakes and engines.
These machines offer a quick, relatively low-cost way for carwashers,
detailers and other professionals to expand their menu of services.
Why should a car care professional consider
a vacuum system for servicing vehicle fluids?
To be able to offer customers more services--and, of course,
to make more money. These systems are not just for changing oil.
In fact, that's only No. 3 on the list for most of my customers.
Most people use them for changing differential fluid, then for
changing transmission fluid. You can also use them for bleeding
brakes or changing power steering fluid. One of my customers
charges $15.99 to change power steering fluid. That takes about
30 seconds to remove a quart of oil, and that's a pretty profitable
service.
Other than eliminating the need for
a lift or a pit, are there any other advantages to using a vacuum
system to change a vehicle's oil?
It eliminates the possibility of a stripped drain plug, for one
thing. It is also a labor-saver, especially with brake bleeding.
One person can operate it safely and effectively. A technician
can even set it up to drain fluid and do something else while
it is working. Another big advantage of these systems is their
ability to deal with overfills. When you have an overfill of
any kind of fluid in a conventional service bay, it takes a lot
of time to put the vehicle back on the lift or do whatever you
have to do to correct the situation. With a fluid extractor it's
very quick and simple--it's about the biggest money-saver you
can have. I have one customer who runs a regular quick lube who
has an evacuator just to deal with overfills.
Do these systems effectively remove
all the oil from an engine?
Even removing the drain plug from the pan won't remove all the
oil from an engine. There will still be about a quarter of an
inch in the bottom and some that clings to internal surfaces.
However, an evacuator will take out just as much fluid as removing
the drain plug would.
Can you use a vacuum system on all makes
and models?
The only make you cannot use vacuum evacuation on that I'm aware
of is Subaru. They have a baffle in the channel that prevents
the tube from penetrating. Some models may need an adapter, and
these are available. Mercedes are built to change oil through
a hollow dipstick. They've been doing it for 30 years.
Does it take any more time to service
a vehicle with this type of system?
For engine oil changes it depends on the oil temperature. If
the oil is hot like it would be in most normal commercial situations,
it takes less than five minutes to drain an engine. If a vehicle
hasn't been running and is sitting around on a cold-say 45 degree
(F)-day, it could take 20 minutes or more. That's because the
tube through which it drains is small. Then there's the filter.
On models where it's located in front and is easily accessible,
it's a simple matter to put some cardboard on the floor and reach
under and unscrew it. Otherwise you'll need a lift or a pit or
the vehicle will have to be jacked up. The transmission tube
is different. It's wider so it's not as affected by fluid temperature.
How much training is required?
I could teach it to anybody in about three minutes. It's very
simple.
What options are available, and what
sort of investment do these machines require?
Systems come in a range of tank sizes with both gravity and low
pressure draining. Features can include wall mounts, wheeled
carts and various adapters. Prices for our line range from $200
up to about $900, and we're probably representative.
Highlights
of An Article in The Arizona Republic by Click & Clack,
a weekly automotive Q & A column, July 19, 1997:
"Dear Tom And Ray:
The quick-oil-change dealer in my town has begun to siphon the
oil from cars through the dipstick tube. He still changes the
filter, and the new oil looks clean, but it seems to me that
debris could be left in the oil pan at the bottom of the engine,
causing problems. What do you think? - Keith
RAY: I don't think it's a problem, Keith. I think it's a great
idea. It'll probably even remove some stuff that you wouldn't
get out through the normal oil-change process.
TOM: Whichever method you use, you're going to get only about
95 percent of the old oil out. But that's good enough. And the
advantage of sucking the oil out through the dipstick tube is
that it eliminates the possibility that some knuckle-scraper
at the quick-oil-change place is going to strip your oil pan
by over tightening the drain plug. So long as they change the
filter, were all for this new method because it makes the job
almost foolproof."
Highlights
of An Article in The National Oil & Lube News
Mystery Shopper of March 1995:
EDITOR'S NOTE:
The following review is part of an on-going series of articles
written by an anonymous fast lube operator who tests and evaluates
products on a "mystery shopper" basis.
"...We tested the EZ1 on all types of fluids including oil,
transmission fluid, water, gasoline, differential fluid, kerosene,
coolants and windshield washer fluid. We've never had a problem
using any of them." (For safety reasons never use evacuators
with flammable liquids)
"The EZ1 is very portable. It stands a little over 30 inches
high with a ten inch diameter tank. When empty it weighs about
19 pounds. It is bright red and easy to see."
"...As for how the equipment held up, I can report that
the probes are still in great shape. The unit has a few dents
and bruises but that is because it was dropped into the pit twice.
But like a Timex, it still works great."
