We have a long standing tradition here of enjoying our factually based oil wars ... Newbies ask us oil questions on purpose, then grin and drop down into their fox holes and cover their ears -- the fun is sure to start immediately.
We have a lot of fun with the questions, but please remember the very best most effective mortar rounds are
completely truth based.
In a sea of perfectly good useable motor oils, we do have to sort out the car ones with the energy stars and the ones that lack the ZDDP levels (1200 ppm and up) that our old flat tappet Savages need.
There is a strong preference for JASO-MA bike oils, but we don't always care for the big price tags that go with them. Not only do they charge too much per quart, they won't always tell us what is in them.
Diesel oils come across pretty good as "known for what's in them" and for not costing an arm and a leg to get the ZDDP our Savage engines require.
Diesel oils do cost less as they are sold in a market where 5-8 big white gallon jugs comprise a normal oil change. Rotella is neat because it is JASO-MA rated as a bike oil, and it comes in the big diesel packaging so it comes at a lower price than all the rest of the JASO-MA oils.
Yes, Bill generally gets "killed" at the end of each oil war, but he seems to take no lasting damage from it -- he's always back pluggin' his Klotz fer the next one.
Klotz is getting better about saying what's in the bottle -- they are using an estorline base oil (built up from smaller molecules) and they are now stating how much ZDDP they are putting in to the automobile non-catalytic RACING ONLY oil.
Shame they won't say as much about the other oils they sell ....
Klotz has been detail compared to other oils 3 times now by 3 different people, and the gist seems to be "it shows no advantage" to the more standard oils we compare it to.
For example, Bill made the initial mistake of going with a 15w50 weight as his preferred contender, and he lost across the board on a data driven comparison to Rotella Synthetic at 5w40 weight, mainly because his hot weight was too high for the Savage engine and it adversely affected head cooling. His heavier weight oil was slow to pick up the engine heat at the head and slow to release it to the crankcase aluminum walls ...
Some of Bill's claims may sound outlandish to you -- until you start to read all the stuff on the Klotz testimonial pages written by all the rest of the Bills out there. We jest had to test the stuff just to make sure it really wasn't red magic like the Bills say, but alas 3 times it has let us down.
I think it is because we testers are cynical unbelievers and the Klotz magic only works for those who clap for Tinkerbell and truly believe enough for the sparkles to start kicking in .....
