Why are motorcycles vandalized or
sabotaged? Revenge. Anger. Jealousy. Rivalry. Envy. Hatred. Spite.
Mean-spiritedness. Just because. All the darker motives of human nature come
into play.

Do you really want
to settle for cheap plastic knockoffs?

A new customer says it best!
“Hi Kurt, I just wanted to let you know how much I like your Locking Oil Caps.
Not only are they ‘made in America’, they look great and work well. I sleep well
knowing the oil cap is locked on and keeping deviants out.
Before I got your cap a vandal poured Karo Syrup in my
oil pan. That stuff mixes well with oil when it heats up - flows like a charm.
Then when you park your bike and it cools down overnight, it molecularly bonds
with the motor oil and coagulates throughout the motor and clogs oil passages.
It’s not a matter of having insurance, it’s being a thousand miles out and
dealing with a dead engine on your vacation.
Yes, insurance paid for the repair, but that’s not the
point. The point is… there are haters out there that can do great damage too
easy. With the locking oil cap, I removed “easy” and sleep well when my bike
isn’t parked in my garage overnight. Thanks Guardian.”

What is

objects entering through an unprotected oil cap?
Stock engine or after-market parts? $6,000. and up
is the figure we have, but it depends upon how much
damage.

STOP!
"Why do I need
this? I have an oil filter."
Your oil filter will not protect your engine from damage due to vandalism or
sabotage. Your oil filter is the very last thing that touches your
oil, filtering the oil AFTER it flows through the
engine. Oil, and anything that enters through the oil
cap, goes into the sump and then to the oil pump,
pumping oil through the engine. AFTER traveling through
the engine is the oil filter - last. Anything added to
the oil goes directly to the pump and then to the
engine. The oil filter is not the issue. You need to
protect your engine from foreign objects. The
GUARDIAN Oil
Protector™ Locking Oil Cap does that.
Locking oil cap cost: 6 cents/day (5 year
example)
Engine rebuilding:
$ 6,000. plus
