Use it and recommend it till the cows come home Could almost say it was made for it 1 Link to comment Share on other sites More sharing options...

So far all I have heard is plausible speculation and no actual facts...not saying anybody is right or wrong but a 100% answer on how a synthetic can cause this kind of wear and why a mineral protects against it would be good...My fg cams are worn and was run on mineral until I owned it....or am I to believe the wear occurred in the 20 thou I've run it on syth.....

Gold Donating Members 23,708 Member For: 16y 9m 9d Gender: Male Location: Adelaide Posted 19/05/15 02:31 AM Share Posted 19/05/15 02:31 AM Right or wrong ull never get an "oiloligish" to definitely say yeh or neigh but Ford and any manufacturer do have people who select oils for applications, reasons and statistics all come into play but what we do know is this Ford are happy to have blends made for an application ( 5.0 S/C ) and don't give a hoot about cost as this oil is exxy as a mofo IF a gain in performance or economy especially economy is there off a simple oil swop they would be all over it People who build performance engines have there thoughts on this and generally for good reason ( outright performance) and if u get top engine builders NOT recommended full syn on a full roller engine you have to at least think why .... Correct ?All broken down to simples as joe's dad has said along with what I've saidTwo rolling surfaces will be inclined to slide vs roll if there is not "gripping" compound A semi has a partial mineral base.... Mineral base is corse compared to full syn If u want two rolling surfaces to roll vs slide what would you do ?Obviously different surfaces/pressures/temps/revs/characteristics will all play a part so you can not tarnish it all with the same brush but u can see at least partially where fords mind is on the barra love it or hate it the 4.0 DOHC is recommended 15/40 semi from people with a few more smarts than us Cheers thanks ta 4 Link to comment Share on other sites More sharing options...

barnz Member 3,047 Member For: 11y 3m 20d Gender: Male Location: Brisbane Posted 19/05/15 03:39 AM Share Posted 19/05/15 03:39 AM That theory jet, suggests that the resistance of the roller is greater than the friction between the cam and the roller, causing it to slide? Sounds good but I'm still not sold. Why then was this not as much of an issue on B series? rollers have not changed between them as far as I'm aware. Also many FULL roller engines run syn from the factory. So yeah I do think "why?" And try and make a logical deduction but this one seems to go both ways. At least for me.Sorry pep should probably have the last few posts move to the fg cams thread if you want. 1 Link to comment Share on other sites More sharing options...
Skids4kids in the mid....not the bum like some Member 609 Member For: 11y 10m 17d Gender: Male Posted 19/05/15 06:14 AM Share Posted 19/05/15 06:14 AM I made a thread on this years ago when my cams flogged out in my BA using the sh*tty level of zinc HPR10 back in the day.Try not to look at ULX110 as just your normal mineral oil also.Very happy with the oil testing carried out on my old stock motor using ULX110 10w50.

bjc Donating Members 2,823 Member For: 21y 6m 9d Gender: Male Location: Townsville Posted 19/05/15 08:59 AM Share Posted 19/05/15 08:59 AM What's the cost of UXL110 10w40? My thinking with mineral vs synthetic is mineral is cheap so that's why it's used for stock cars...As for engine builders recommending mineral or whatever I'd also have a guess at that's originally where they were at using it and so continued with it but also that the big hp engines they build have oil changes after every drag meet and or every run...I could be wrong though but after all these years I still love the royal purple but generally can't afford it anymore (20% off at Supercheap I grabbed it again though!) and went with what allot have used which is the Nulon 10w40 full syn. Mind you with all of this I have never seen inside my engines nor have I destroyed one either!I think on this subject we all agree to disagree 1 Link to comment Share on other sites More sharing options...
