Bill is once again throwing out his banana peels of misinformation, intentionally tripping up the innocent newbie readers.
But that's what Bill does -- he knows he will provoke yet anther oil war which he will lose again, but he does love them so much he can't seem to help himself.
=============
Car oil is car oil, it is built for current car engines which have catalytic converters and roller tappet cams.
Why roller tappets? Today's catalytic converter equipped car engines cannot have the old style effective anti-galling additive packages referred to as ZDDP which kept cam lobes and old style flat rocker tappets from getting indigestion. So the modern pollution controlled engines have to have fancy anti friction roller tappets so they can survive without the additive package ZDDP. Remember, ZDDP and catalytic converters do not get along.
Any modern car oil lacks the over 10 PPM of ZDDP that your Savage engine needs. You don't have ZDDP watch your rocker arm flat tappets gall and "dish out" over time. Watch your cam chain stretch and wear out prematurely.
=============
Two places to find ZDDP in concentrations over 10 PPM -- motorcycle oils at over $10 a quart or diesel truck oils at circa $11 a gallon at Wal Mart.
Do the math -- $10 a quart, or $10 a gallon ..... hmmm, let me see which one costs less.
=========================
Now here comes the oil war (and another 2 dozen banana peels from Bill about JASO ratings on bottles)
BTW, before Bill gets there with his banana peels
JASO is a Japanese rating system that is similar to ASME ratings that we are all familiar with. The heart of the JASO tests are the wet clutch performance tests for motorcycles which many modern American car oils fail miserably because of energy star friction modifiers that are put in our car oils to help get better car gas mileage (while not harming our required catalytic converters).
Energy Star burst on the bottle -- poison for your clutch (remember this)
=============
What inexpensive gallon jug sized dino oil passes all the JASO clutch tests, HAS the ZDDP your Savage engine needs, does not have any clutch killing energy star additives and costs $11 a gallon at Walmart? Which one has passed every oil war on every list and has a history of sucessfully passed oil analysis going back 5 plus years at Bobistheoilguy.com?
White jug Rotella Triple Protection diesel oil
This is the MOST POPULAR best respected motorcycle oil in America based on gallons bought and used. If you don't think so, punch it into your browser along with the word motorcycle. Watch the year dates on your discussions though, two years ago all of the Rotella oils got updated and retested to JASO because of an old issue with ash levels (which was fixed pushing two years ago because bikers are very vocal customers).
And it has a big brother in the blue jug for $19 a gallon at WalMart, the ever popular Rotella Synthetic with Extreme high temperature protection. This is the stuff we are monitoring on list threads as more list members begin to use it as it has a tracking history of improving our shifting, allowing more free engine revving and <still controversial> improving our gas mileage.
(It also has two folks reporting increased oil usage, which is unfortunate but also is being reported)
============
So, where does this budding oil war go from here?
BTW, there is nothing wrong or lacking with your Valvoline 20w50 motorcycle oil.
