It'* the one in this pic:



If you'd like, I can take a pic of it next to the OEM size filter I just installed for the first 100 miles on the Zilla. This one goes on next. I can tell you the physical size difference is remarkable. It'* more than twice as long and probably larger in diameter as well.

Macdrive, it is an interesting question you pose about the oil and it shows that there are people out there thinking that way. That'* okay. People are still free to think what they choose.
Good you came and asked for an opinion and too bad you got judged for it; it'* a FORUM and some love it so much that when an idea is described that does not appear to be on centre then the author sometimes receives something akin to being flamed. That is obviously not necessary in a forum where everyone wants to help others. Again, not much one can do about another'* friustration level other then to extend some grace.

Anyways...

My opinion - follow the manufacturer'* specs on the oil capacity (but not on coolant type and thermostat evidently ) and your car will fare better.

Cooey, please do a Forum search on the word OIL with MACDRIVE as the author and I think you'll gain a better understanding of just exactly what'* going on here.

I dont see the problem with Mac trying to get as much knowledge about oil as he can. Seems harmless to me. This the intent of the forum, is it not? To share knowledge and brainstorm any and all Bonneville related topics?

Toasty, I'll answer your questions privately if you like. Or read the GH section to get a better idea.

It is a damn shame that noone in this thread was offering any type of constructive dialogue based on the ORIGINAL QUESTION.
READ THE TITLE - It asks WILL it hold 6 qts... NOT should he run it. Everyone is simply telling MAC not to do it and to stick with manufacturers specifications, and not offering any FACTS whether or not he can run extra oil safely, but instead listing what can result of overfilling, and not providing an actual amount known for a maximum capacity without causing the (well needed) heeded warnings . Why? Because no one here has done in and therefore no one here knows. The result is 2 pages of useless posts of nothing but bashing MAC DRIVE for trying to gain the most knowledge from the most respectable and knowledgeable Bonneville community in the world. We should be embracing his inquisitive nature and teach him as well as perhaps learn something new for ourselves.

As you can see, Toasty, he'* specifically referring to over-filling it. That'* why we jumped on it. We can't afford to have an idea turn into something some noobie will want to try. That'* why the warnings and debate about it.

This is a very bad and dangerous thing to do. It needs to be made VERY clear why overfilling is a very bad idea.

On the other side of the equation, you have to understand that everyone here is human. And the level of frustration about oil topic after oil topic after oil topic after oil topic is getting a bit frustrating. Particularly when they all come from the same person.

This is how it works, in a sense:

After a number of posts like this, nobody is going to take you seriously, and at least a few are going to be frustrated by the sheer number of posts on a subject like oil.

From my point of view, we made the point very well in this topic to protect other members from the effects of a bad idea.

I've got about 5.5 quarts in since I filled it then put in an additive to try to buy a little time til the new motor was here and all the little parts I have. It'* about 3/16" above full on the dipstick. Seems to be alright for the time being. I'll run 5 quarts, no more no less, in my new motor.

If I knew I'd be putting in an extra additive, I'da put less oil in.

Bill, any fitment issues with that K&N oil filter on the 92-99'*? Specifically ground clearance? I'm not sure if this one is like the other slightly longer ones that others run.

I'll let Wren confirm it for your body style; but i can't imagine how you'd have any issues, especially with the ground. It'* bigger than the stock size filter but mine was nowhere near having any sort of ground clearance issues.
