what brand, type, and viscosity oil does everyone use?

[Thunderchicken205]

I am about to change my oil again. I have always used Pro-Honda HP4 but was interested in seeing what others were using. Do you use full synthetics, synthetic blends, traditional oil? What brands have you had good luck with or prefer?

I have been running Motul 5100 10W40 for quite awhile. It is considered a Technosynthese oil, fancy name for semi-synthetic. I am thinking of switching to a full synthetic next time.

[Thunderchicken205]

cool, appreciate it. So youre using a blend. On a similar vein, i've heard people say not to use full synthetics. I dont know if they know what the hell theyre talking about, but it makes me wonder the reasoning behind it is.

I've recently been running Castrol Supersuckersynthemobikecrap 10w40 for bikes. That means I can't remember what they call it. When I was in the states I plumped for Mobil One bike oil.

I don't know much about it, but supposedly synthetic is better for engine internals, but natural is better for wet clutches. Also if you run any dino juice, it expands the oil seals, and going to full synthetic afterwards may cause oil leaks. Then, this could all be a bunch of snipe hunting as I can't remember if any/some of it came from a reputable source...

Shell Rotella T regular dino oil.
I was told not to use synthetics in older vehicles.
This was from an old timer, some of his reasoning was seals and clearances. I follow what he says because he has never steered me wrong. Plus I change oil often so...
I tried synthetic in my '73 corolla and it sounded like it was coming apart.
Back to Rotella and it was fine.
That rotella is for trucks and seems pretty tough. I think these motors are hard on oil; lots of load in a Vee twin.

I've been running for about the last 7 years the Mobile1 Racing 4T 15w50 full synthetic oil in the "specially filled for Triumph" 4 liter jug. Super frickin expensive but works awesome on the Hawk and others. Even keeps the gearbox pretty smooth and the engine running cooler in the hot months. I use it on any of my twins, Ducati, etc...

Pay special attention to the paragraph on VII's (viscosity index improvers) long molecules added to some oils to increase the high temp viscosity, they get shredded in the gearbox and don't work as well. Thats what influenced me the most.

i run good oil and change it very frequently.

if you do the same, then you'll never have to worry about it.



i used to jump and preach and go on about motor oils... but really, if you just change it and run good oil to begin with, it doenst matter that much.


that said, just stay away from wax based oils. lol.

What ever's on sale (dino only)
change it too oftain to bother with synth

[GatorHawk]

Been using any quality dino 15W-40 oil for South Florida temps. A while back Advance Auto had Gallon jugs for $5 after rebate.

Haven't had any problems with using this viscosity or type of oil. I do less than about 5K miles per year but still change out (with filter) every 6 months regardless of mileage.

You can get swallowed up by all the 'gospel' and such at bobistheoilguy.com. Eventually, I realized that time was better spent doing other things and settled on the above regiment.

All I run in the CBR1000RR , and what I will run in the Hawk when its rolling again...

yeah... I'm with MrDude... If you just change your oil on schedule you can use the cheap stuff vs. the expensive stuff like Motul. I have never had a problem in all of the MC's I have owned and TONS of oil changes I have done. Plus if your riding on the street... does it really make that big of a difference in terms of engine performance? How many of you guys ride near the redline everyday (vs. at the track)? My opinion and all my racer buddies opinions are that the good oil really only makes a difference on hard ridden engines like at the track. But that's just our opinion... If I had more money I would be dumping only Motul Candy into my engine.

Any old 10-40 mineral stuff and changed regularly.
