your choice-for sure

we are all different with what we like + are willing + able to spend. i am just pointing out the differences in products. you can run cheaper oil + change it more or not until problems show up. i had Amsoil 20-50 in an 06 porkster, stored in an unheated garage say 40's, roll out to ride on a sunny almost 60 degree afternoon, it grinds slowly + will not start. battery it topped up, enter 10-40 fast cranking + startup. common sence tells me the 20- whatever is too thick + prolly not getting to critical parts + causing excessive, again its your choice!!!

They all have diesel on them.

I did a series of three lab tests with Rotella T, 15-40 Rotella T6, and a combination and the combo tested best. All tested good with LOTS of life left in them.
Were you able to determine what weight your combination created? I think choosing the right weight for climate and the factory recommendation is the most important consideration. One thing I know from first hand experience is the oil pressure created in your motor is proportional to the oil weight so the manufacture may be suggesting a certain weight to obtain a required oil pressure for the motor.

I know a lot have mentioned they have had no issues with their choices of oil however as stated by a few, there is no way to really know until a catastrophic loss. I would love to see a comparison tear down at the end of a motors life based on oil type and weight.

Good thread with a lot of good info. I am new to the MC world so by no means am i claiming I am a expert. Just sharing first hand experience from wrenching.

5W-40 and 15w-40 is still a 40 weight that didn't change.

the unknown!!!

manufacturers have NO idea of the temperatures YOUR motorcycle-oil will be subjected to!!! hence a BALLPARK recommendation + unlike cars + trucks with tightly controlled cooling systems our engines get hotter VERY hot at times. as i noted before oil specs are at 40C for the first # and 100 C for the last both of which we surpass regularly!!! i used the RECOMMENDED 20-50 in my traded hardly it would NOT start in colder conditions, it cranked then killed the battery!!! Amsoil no less which may have already been using group III oils that thicken more when cold than real synthetics + thin more when hot. i believe any decent oil changed regularly will be fine, but lower first #'s start easier in the cold, + higher second #'s can be more protective in the heat. real synthetics like red line are better cold or hot but cost more. its NOT about the best oil but the best oil for YOU + your WALLET!! you will never hurt an engine with better oil or more changes but on the opposite end xtra wear + possible engine damage can occur!!! your choice your $$$ your engine will live on thinner oils with added wear + a little more power, but it will live longer with a thicker oil film aka higher viscosity oil!!!

W= winter

the first # as noted before the W is the viscosity @ 40C aka 104F, do you think your oil in your engine is that temp when your bike sets where its 32F!!! that means your oil is NOT an advertised 5, 10, or 15 viscosity at that time!! its a LOT thicker aka less vicious!! i was looking for a table i seen that shows how much thicker mineral oils get in the cold vs true synthetics, its a lot. when i find it i will check back.

Thanks for posting the main reason I use Rotella T-6 5W-40. Much faster circulation, faster filling of the hydraulic lifters. The lifters used to clatter something terrible on the recommended 20W-40, even in warm weather startups. And the heavier additive package of Diesel engine oil protects our engines that much better.

When I put the Vic to bed (Oct 15th) I put fresh T6 in it for the first time. She has yet to come out of mothballs this year, but I'm hoping when I fire it up she won't sound like like a blender with a handful of marbles thrown in like she normally does. I had used T6 in my Valk for several years. I always changed it out at 4 to 5k mile intervals. Before I retired I drove an old VW bug to commute 100 miles a day. I'd save the drain oil from the Valk and used it in the VW to keep it topped off between oil changes (4 to 5K miles w/ spin on filter & valve adjust). That VW motor ran for 100k miles before I swapped it out due to oil leaks making its mark everywhere it was parked.

A sig with model, year and mods will help us to help you. Some here are getting weary of those who refuse to fill out their profiles and sigs. They come here begging help from us, the least they can do is provide us something to go on that will help us to help them.

Tried the t-6

Old thread I know but just wanted to say that I tried the ROTELLA T-6 and I haven't noticed any difference in anything about the engine. Next on my list is the Amsoil 20-40

I was quite surprised at how much smoother and quieter my 04 ran on the Amsoil 20w-40. I think I'll be putting it in the 11 at the next oil change. I hear the Spectro, made for Vic's, does quite well too. Price is close to the same.

those in hotter climates would be better served with a 20-50 real synthetic, or my fav a 15-50 real synthetic like the spectro platinum PAO i changed to + although i ride little in colder weather i like the quieter starts with it + the superior film strength of a 50W at running temps

Between you and Broggy; you've convinced me to try the Spectro 20w50 Platinum synth next time in my 11 XC.

I ran the Amsoil 15w-60 last year and it by far gave me the smoothest shifts and quietest valve train. Right now I am running The Castrol Power 1 Vtwin 20w-50 and I like it as well. Shifts are good and almost as quiet as the 15w-60. One of these days I mights actually get around to getting an oil analysis done.
