Scott, was not able to respond to you on the thread "modern day machining". Yes, I choose synthetic Mobil V-Twin oil, I have run Mobil syn since they first marketed the stuff. My wifes Nissan Rogue and the Road Star even use the same Oil filter which I load up on when I find A sale. I do not consider the Mobil One V-Twin oil the best synthetic on the market. I believe the best are Motul, Redline and Amsoil. The full synthetic Yamalube probably a better product than Mobil also. I refuse to pay those prices for oil.The Ester based products far outperform. (thermal breakdown)If you have that great a concern about percentage of zddp, zinc additives you might look into diesel engine oils. There are good options in that category of oils that will work great for our RS's. Just my .02 cent worth. I mean hey, it's just oil!
Hi dirk,Am step ahead of you on that one/LOL!!!!
Your not aware of the fact that i have been researching & testing motor oils(some diesel ,some pass car oils,couple bike oils too while i was at it) for past few yrs for team chevelle with respct to FT cam'd muscle car motors . I can tell you from my exp digging into this for yrs now it's not just oil like there's not much diff between the oils when it come's to protection,there shure as heck is a difference .
But 1st things 1st,on the diesel oil you reffered too,most diesel oils dont have enough zddp anymore since 1/2007 in the newer CJ rating,but pre 1/2007 older
CI rating diesel oil had enough zddp to protect most FT cams even perf ones running higher spring rates. But chevrons delo LE 15w-40 in thr newer CJ rating is a diesle oil sold today that still has enough zddp to protect stock to mild FT perf cam's .
There are plenty of oils avail today with proper zddp lvl to protect tf cams but you have to know where they are because most arent sold over the conuter anymore . So if you would like that list pm me your email address and i will send you the list i compiled woth oils sold today with decent zddp lvl required for safe Ft cam protection.
And many oils sold today have Fric mods too reguardless of grade which i have confirmed from contacing mult oil mgf's which confirmed that was the case so its not just light grade fuel conserving oils that have fric mods anmore as is often mis spoken here in RSC. Heck i noticed the other day it even states that fact it has fric mod's in it on the back of valvolines VR1 race oil with good zddp lvl for safe FT cam protection in classic & muscle car motor running FT cams.
BTW,there was an extensive oil test done late 2009 and Amsoil /Mobile 1 v-twin bith fully syn in 20w-50 came out on top. There were 17 oils tested in 20w-50 grade and those oils came out 1 & 2 resp,yoiu motul came out in 12th out 17 oils not doing that well. This is by far the best oil test i had ever read over the yrs done by qualified people.
The mobile 1 v-twin did very well against other oils,only amsoil did alittle better and not by much
IMHO. But i have to agree i also not all of mobils 1's semi or full syn oils are all that great,but Mobil got it right with the v-twin full syn 20w-50 which extensive testing showed ,thats for sure.
and when i swithced to mobil 1 v-twin fully syn 20w-50 in my R* the motor ran a little smoother and completely guiet even on hot 95 deg HHH days whichother oils could not do in my bike's lrg air cooled FT cam'd motor & would get clicky/ticky esp in top end/valve-train which isn't an issue not with the mobil1 20w-50 v-twin oil in my bike.
So if you want to to see just how good or just how poorly some big name oils perform then you need toread a very good extensive oil test done on 17 oils from mult mfg's that explains each test very well so you understand what is test is and what imporance it has go to this link.
The test was done on 10w-40 and also 20w-50 grades in ,some in conventional/some in semi blend/some in full syn. and i can tell you if youread that test rept i bet doing that will change your opion/view of oil you have at this time. The oil testing was very coplete and done extreemly well and show njust how much of diff there is betwwen the oils as far as performance/protection goes and that in most case you litterally do get what you pay for when it comes to motors oil for bikes and i have seen the same thyp results in car motor oil testing over the yrs too,some do well and tohers dont even in well repsected name pass car oils.
