What to do if your bottles don't
When the BOB was designed in 1992, all motor oil bottles had the same neck
diameter of 1-1/4 inches. Then, Mobil One, Castrol Syntec, and some others
came up with new designs that were bigger than the BOB receptacle. Weíve
considered producing adapters to accommodate these bottles, but that would
just be an added expense for you, our valued customers. So, hereís a method
to make your own adapters for bottles that donít fit or wonít stay in the
BOB trough. Itís simple, and best of all, itís free!
Obtain some old oil bottles that have 1-1/4 inch necks, like Chevron, Amoco,
Texaco, or others. (House brands usually have a good bottle.) Using a razor
knife (be careful!), cut off the tops of the bottles to the dimension shown
above. We donít recommend using a saw, since the little bits of plastic
will contaminate your oil. Put these adapters into the trough and put your
Mobil One or other big necked bottle into the adapter.
We've been in contact with the Mobil and Castrol people responsible for
the large necked bottles, which really negate the whole advantage of plastic
bottles, that being the ability to pour into an engine without the need
for a funnel. The large necks are European styles, so these manufacturers
are just trying to be stylish, without regard for functionality.
The original bottle designed for use in the United States is the small
1-1/4 inch neck. One of the people who designed the small necked bottle
told me they designed it specifically so it would fit inside the filler
on most American cars. Nobody can really figure why Mobil and Castrol went
to the big necks for American markets in the first place, since they don't
fit American cars. The consensus is that the extra cost of the product
requires a different, more expensive, container. If you have any
comments you'd like to have forwarded to Mobil or Castrol, send me an email,
and I'll make sure they get it.
