Then how does Harley get away with advertising that their Syn3 oil is a full synthetic??

 

====================================

And I'll guarantee you it Won't be 20 degrees cooler... Worked 41 yrs as Machine-repairman in one of the big 3 Auto dealing with Gear-boxes almost everyday and I can say Syn oils last longer in High Temps... """BUT"" they wont lower the overall Oil temp that much... Now if you'd said 3-5 degrees,,, I'd agree but no-way will they drop the temp 20... Your been reading or listening to the Cool-aid the a Famous Oil company puts out.. and it ain't Mobil 1.....

I did the usual stg1 at 1k on my bike and put in Syn 3 back in 08 on my 07 and it did drop the OIL temp on my Dipstick Temp gauge.. (((but))) it was only about 10 degrees total....

The most difference and Drop in Temp on my oil DipStick was achieved when I changed the cams.... then I got almost a 15 Degree difference.....

I don't believe any OIL can made a major difference (over 5*) in OIL Temp Alone!!!! just me and My experience ......

 

Back on topic.

I've been using the Quicksilver Synthetic 20-50 for about 8 months now. I haven't had any problems with it.

 

It depends what you mean by Full Synthetic, first off almost oil the oils mentioned in this forum and 90 percent of oils on your store shelf are not true synthetic oil. True synthetic oil is made out of something other then dino oil.

In the USA, by Court Ruling, ANY oil can be called Full Synthetic if it behaves in the same way as a non dino synthetic oil. Almost all the oils mentioned in here are made from or contain synthetic oil made from oil.

In Germany, synthetic oil can not be called Full Synthetic unless it is made from something other then dino oil. so for example German Castrol Synthetic oil is truly, synthetic oil, made from something other then dino oil.

USA Castrol Synthetic oil is made from Dino oil.

In the USA as long as a dino oil called Full Synthetic performs like a true full synthetic made from something other then oil, the USA courts recognizes it as synthetic.
More or less, the courts do not care what something is made out of as long as it performs as it is labeled.

Years ago there was a bid lawsuit over this between Mobile and Castrol, Castrol won and opened the door to any oil being able to be called Full Synthetic no matter what it contained, as long as it could be proved to behave in the same way as the real thing.

 

im not an oil professional,but i would like to hear from an expert,about the blends,indifferent kinds of oil,and whats the difference? i mean harley davidson could take a pair of sneakers,put the trademark on it like a lot of items out there that are made in china,and the can sell it for a Hundred Dollars,but where talking about oil here.harley davidson oil vs quicksilver synthetic,i mean scientific facts,anyone out there??got facts?

 

alot of material to cover on oil,but like someone said as long as it does what it says it does then its ok< lol

2 Year old thread.

 

I found this on a search from quicksilver site. Take it or leave it. Me and my fiancé are going to try it out. Quicksilver seems very confident in there product.

I have been a Mobile 1 user but getting the 5qt jug of 20w-50 is getting harder. Seems they want you to buy oil in 1qt bottles so you pay more $$$.

 

You could invest on a good filter, Harley Davidson run hot I like to replace the oil at 3000 miles or close to it. The oil get so hot the color changes I like my oil to stay clear. $31.00 a gallon is a Bargain is a guy on you tube that did a Test comparison with all the 20 W 50 the end result was they all do the same. So if you want to spend more money for the same know yourself out. My oil is clean and viscocity is good she have ridden all over the US on Quick SIlver no issues. But then again I keep it running in top notch good maintainance is the key.

I have seen you make a few comments about "oil is oil". I will never understand why someone spends the amount of money that a Harley costs, only to dump garbage in the engine.

If you have to buy Wal-Mart oil, or any other oil that you pick up at the local Big Lots, then you don't need a Harley.

Chances are, if you have never heard of the oil, there is probably a reason.[/QUOTE]
