I've got 12k on the bike and am ready to switch to synthetic. Any consensus on which is the BEST?
Just search Jestal's writings.

BTW - do you still have that fuel cell for sale, or did Groo get to you?

Fuel cell is still for sale. Haven't pursued it yet. Thinking about putting it on eBay cuz you fellas both jumped on this so fast. Not sure who to go to...

 
Hmmmm.... I have received 3 private emails on this thread asking what I personally use, so although it's against my better judgement to even reply to this intemiable NERPT, I'll offer my opinion on the two synthetic oils I used religiously nowadays....

On the FJR, it's Mobil One 15-50W red (or gold) cap (no starburst label, obviously). It's readily available most everywhere, and when on sale, not too shabby a price.

Between November-April, I'll switch to 10-40W Mobil One MX4T.... PacNorWest winters here in the steppes and plains in the High Desert of eastern Washington can make conventional oils the consistancy of pudding (ok, slightly exaggerating here, but....)

However, for the XX and the R1, I have made the leap to a slightly more expensive synthetic, which may or may not be superior to the MX4T stuff, but I get a woody using it, so.... :lol:

The XX and R1 receive this delicious oil here: Silkolene 4T Pro-4 Plus Synthetic Racing Engine Oil

Yeah, it's probably way overkill on the R1 (where I use the 10-40W version of this Silkolene), but the Blackbird is another story. There are events where I wouldn't be surprised if the oil temp gets overly, brutally hot.... perhaps not over the 305F mark that jastel mentions, but events like BLISTER, White Pine Fever, ect are exceedingly difficult on the powertrain.

Which is not surprising.... loading the bike up to max GVW and locking the throttle at 8500 RPM for 24 to 48 continuous, non-stop hours in the mid-July Desert West.... this is some fairly severe duty, you'll agree. :blink:

i'll weigh in --

Technically: Yamalube will work fine -- change as recommended -- you won't have problems.

But no different than extended warrantees -- if it makes you feel better about it, or more confident in the reliability -- use more expensive synthetics.

Personally -- I use MX4T in my Aprilia, Mobil 1 in my Trucks/cars, and Rotella T (synthetic -- blue jug) in my other cycles (FJR, V-Star, DR-Z, LT6500). Use OEM filters or Pureolator PureONE filters.

and I feel good about it... find what makes ya feel good -- and do that.

 
On my VTX (also wet clutch) I ran Amsoil, never had any problems granted I didnt put awhole lot of miles on it in a year and a half. On my corvette however different scenario. In just under 3 years, I put over 50k miles on it. I originally used German Castrol 0w-30, and sent off for oil analysis reports. I met a guy on the corvette forums that wanted to do some testing, so we ran a few runs of amsoil and did the analysis after those. The amsoil outperformed the german castrol, enough to make a believer out of me. Keep in mind, I drove the vette like it was made for. It went to the 1/4 mile track, and was dyno'd a bit, and probably kissed 155mph a few times (on a closed course of course)

I originally wanted to use the mobil 1 mx4t and get that tested, but couldnt, so amsoil was my choice.

 
Shell Rotella synthetic available at wallyworld for about 15 bucks a gallon. Their super tech filters are just fine also.

However if you want to spend more money to make you feel that other products may be better, go ahead and feel good. The bike won't know the difference!

I think that you can get yamalube for a decent price if you look around on the net and if you buy the yammie filter too - well your life will be sanctified and you will live longer and happier according to mammy yammie or at least your bike will :D

 
Just throwing this out there - has anyone done oil anaylsis on all these different oils? I'm willing to, as long as I'm not duplicating work already done. I know we have resident experts on the matter, but similar situation on the corvette forum. Quite a few people over there know alot more about oil than I ever will, but having oil analysis' in front of you takes out any guestimates and opinions. It is what it is....

 
Of all the suitable synthetic brands mentioned above (Mobil, Rotella-T, Amsoil...), the BEST oil is the one that is readily available to you and has a price you are comfortable with, so that you will change it and the filter as scheduled.

I'm of the camp who doesn't believe synthetic is necessary in my FJR or allows longer intervals between changes, so I buy what I can afford to do every 4000 miles, which frees up some coin for the GM EOS and all those handsome OEM filters I go through.
 
Buy a simple cooking thermometer or other thermometer with a probe. Ride your FJR as hard as you think you can possibly ever ride it. Stop and immediately open the oil fill port and stick the thermometer into the oil.
Note to self: Pick up digital probe thermometer for last ditch attempt in case of radar detector failure.
"But officer, I was running a highly advanced test to see if I need synthetic oil".

With a first name of Robert, maybe I could convince him that I'm Bob The Oil Guy.

Otherwise, you are just wasting money. It it makes you feel good that is fine but technically the only advantage synthetic will have is the high temperature capability (above 305 F)
"Wrong" Synthetic's also flow better when cold. They also run cooler. They also show less wear. They also leave less carbon deposits. There are many benefits to running Synthetic oils. These are already proven facts :rolleyes: . "I just couldn't help myself" :glare:
