Read my post again boys,, never said it doesn't run cooler and never said it is not as good as dino,, both claims might be true however, neither of you know that for a fact BUTyou both state it as a fact.. I want to hear about
Hands-on experience, not what you read or heard or believe..
You see rj, I don't need to measure syn oil against dino oil because I'm not trying to prove a claim, I simply reported my experience..
You made a claim but you offered no basis for that claim, only a suggestion for others to make their own measurements after two different oil changes and re-fills.. Heck by that time the seasons temps have changed and maybe even traffic patterns.. Gosh man, all you did was lay down a claim and suggest others prove it for you----------do it your self baby,,
Hands-on first-hand experience talks everything else walks..
Ok, soo, did you ever actually make those measurements yourself rj..??

The only personal experience that I have with Syn oils are with my cars, over many years. Iv'e owned German cars that come from the factory with syn and 9000 mile recommended oil changes. I have had techs at the jap car dealership (who offer a free oil change with any other service work) tell me that I can run double the 3000 miles recommended for dyno oils. I like em.
I was at my dealers and a guy came in complaining that his trans. seemed to be making more noise than usual. This was 1500 miles after he left home. When the tech. checked his transmission there was no oil in his transmission. He was running SYN3 and when he drained it for his journey west, he forgot to refill it back up with more SYN3. So he went 1500 miles with what ever oil was left clinging to his gears. I don't know if dino oil would have been just as effective, but I think it speaks highly of synthetics. There was no damage to his transmission as far as any one could tell and sounded fine after it was refilled with SYN3.
Synthetic is absolutely an advantage in so many real ways it's simply ridiculous to hear any educated mechanic say not to use it. I would have to find another mechanic ASAP! This guy was backing Castrol ?- I read they've been cheating their customers, selling "Fully Synthetic" oil that is really a "Blend". Apparently they found some legal "loophole" that allows them to do this. Nice!
Even on a new bike and as smooth as the V-Rod you can feel the difference. Shovels and older Evos will really see a difference. There is simply less friction and with less friction can come many benefits. Besides I don't understand the controversy, It's not a whole lot of money to use it so why not? Hell 4 quarts costs less than the amount of beer you'll piss out this week.
My pet peave is are the people that keep telling folks you haveti run dino during it's break-in period. Pure BS. Since when is making a motor run easier and with less wear and tear from the get-go bad?
I've broken in my Evo, after its rebuild, my TC95, and 1200 Sportster with dino then switched to syn. Why? Cost. I'm a freak about changing oil at break-in. I change it at 50 miles, then every 500 miles until 2500, when I figure all the shavings, etc are out of the motor. I'd hate to foot the bill for oil if I were using syn for break-in.

I do the same, maybe even more often for the first 1500 miles. But I use synthetic oil.
I'm simply asking folks to do a simple experiment. I can sit behind a keyboard and make all kinds of claims, but it won't amount to anything unless you can see it for yourself.
There is nothing wrong with running conventional oil. It is the benchmark by which all other oils are measured.
I do monitor my engine operating temperature both the coolant (it's a V-Rod) and the oil temperatures. I also monitor the fan on and off temps, and I also run wideband 02 sensors on my bike. I'm a geek that way.
Gee this is always an interesting topic. Isn't like - do you prefer blondes or brunettes? I ran Mobil 1 in my 1997 EVO - I changed it at 21,000 miles. I liked it - seemed to make less noise to me. When I sold it with 60,000 - I had had no major engine problems. Used less that a quart of oil between changes at 4,000 miles. After the break in period on my new Ultra - changed everything to syn3......so again - I like it - I use it. It works for me.

Nothing sucks more than that moment during an argument when you realize you're wrong.
I doubt they run the 20F coller some sellers claim.
A major advantage to Syns is heat resistance.
They can take more of it, and in our, mostly, air cooled twins, that's an issue.
I'm a firm believer in Syns when they make sense, and they do for our crancases. My personal science experiment on teh trannies and primaries is still running on the 3 bikes at home. But If I had to decide with no further evidence, Syns all the way.
If for no other reason then then I won't change the primaries and traniies as often. And I won't worry about along the way.
Frisco makes very good points, but i'd like to point out a couple of things. In a 20W-50, there is no diff in car and motorcycle oils. The blends for economy that happen in the light car oils do not apply to 20W-50s.
Using a car filter is good, more capacity to filter never hurts, even if you don't really need it, also, the larger filter can provided a cooler effect.
As for Castrols "Synthetic" It's synthetic because a court said so. ANd it MAY be legit. What they did is superrefine fossil oil so that the molecular structure is uniform, same as a regular Syn.
I can't decide if I like that or not.
As for the shop trying to convince JC thsat fossil is better. Bull! plain and simple, BULL****.
Go back to what works for you.
Probably more like, if it ain't broke, don't fix it for them.
That and the half tanker they have out back.... Which is a bad bad idea, btw. Oil has a shelf life until you start using it. Settling, dontcha know.
