Good Stuff.!!

I use the 10w-40 Semi-Synthetic with 10% of the Heavy Duty Oil Stabilizer in all of our bikes too!

What can I say other than it works, no pun intended. If you use or have used some you know what I am talking about.

A tip is to add 10% of the Heavy Duty Oil Stabilizer to the total refill capacity (90% oil / 10% HDOS) when doing your oil changes. If not comfortable using the 10w-40 there is a 20w-50 available or even the 15w-40 TBN Diesel oil too. The HDOS will not make your Clutch slip!

The “Synthetic Heavy Duty Oil Stabilizer” may cause some slipping if too much is used. (I experienced that during our 50cc days mixing / adding with full synthetic 5wt oils).

Our 2008 KX 85 has only gone through 1-set of clutches during four plus seasons of races and non-race practice sessions, using the above 10w-40 set-up described above.

My oldest Step son uses it in his bikes (250F & 450F) for the past few years, races in the +25 and Pro classes and experiences no problems whatsoever with the 10w-40 or the 20w-50 mixed as mentioned above.

Nothing like a good oil discussion - a thread that even the mechanically useless can participate in.

worcs and peely: Far be it from me to tell you what to do. Just want to throw this out there. You do realise what you are using is a modern oil made for a high temp, high soot, EGR diesel engine found in trucks, correct? As in the N14 Cummins I run in my RIG! Not exactly a moto application. All the additives they jam in that jug to make it work just won't be good for your clutch, long term. If saving money is all you are concerned about, maybe just go with Wal Marts own 10W30 automotive oil. At least there's LESS crap in that. The rule is now with these new CI oils is that there's more additives than oil in that jug. Being in the biz, I'm somewhat familiar with what's happening. Unless you're planning on throwing a 5th wheel and a Jake Brake on your bike, maybe switch to something a little more compatible. Although the Jake would let you slam the brakes on harder and later for the corners. Add some straight pipes and you the MAN!
IN talking with a motor guy, he swore by Bro-tella and his reasoning for it is that no M/C specific oil has the rigorous testing that Rotella does. If it can hold up to the abuse a long hauler can give it than I think an hour or so in my bikes would be no big deal for it. Hes a fast local pro himself, and he mentioned he had the same clutch in his RM-Z 250 for nearly two years. It may not be ideal for an MX bike but bikes are going to wear out clutches no matter what, so I may as well preserve the rest of the motor. If only they offered that oil without all the additives.

I tried out the Lucas motocrycle oil available at any ole auto parts retailer, their marketing worked on me, but that stuff is garbage. It broke down in about half the time, and felt like it was just straight up dissolving my clutch. When it came out of the bike it had a very 'gritty' feeling and seemed that the clutch started fading way before it should have.

I got a question for the TALIBAN, If I were in a pinch would running out-board 2 cycle oil available at the gas station be a no-no?

A 2 cycle outboard works a helluva lot harder than a 2 cycle dirtbike engine. Use it, its fine.

Sorry to hear that.

That is the first time I have heard anyone have a problem when trying the Lucas Oil. IMO there was another problem / issue going on that caused the Clutch breakdown and it was a coincidence that it happened at the same time you tried the Lucas Oil.

I use Mobile 1 synthetic 4T 10W40 oil. I was doing a creek crossing and dropped the bike in the water. I pulled it back to the house (2 miles away) and the whole time trying to bump start it. When I got back to the house and emptied the oil, it was definitely apparent that water entered the engine and oil casing. After spending some time cleaning it and got it started, it's ran just fine without any valve adjustments. This is over 2 years ago now. Also, recently a bolt came loose which drained all but a small amount of residual amount of oil. Again, absolutely no problems. There is a mechanic (GrayRacer) in the ThumperTalk YZ450F forum and he has posted an insane plethora of information on oil viscosity, additives, breakdown periods and anything else you want to know about oil. Mobile 1 and Amsoil were at the top of all experiments performed.

I use Amsoil 10w-40. Link to this experiment you speak of?

Possibly, but I ran it in both my 250f and 450f Hondas during the same period of time and it had pretty much the same result. maybe saying it was garbage wasnt a proper representation of how it worked. It did alright, but compared to Rotella it had nowhere near the life/durability. Rotella has been good to me and my bikes so it kinda of hard to switch once you start using something. Its cheap and easy to pick up while shopping at wal-mart, but maybe I'll have to try out Lucas again... at least the Tranny fluid for my two-stroke.

i use Shell Rotella from walmart, 13 bucks a gallon and it is good stuff as long as you change it regularly.

i usually change it every other ride though
I use shell Rotella in my race car from what I've been reading I guess I will use the same oil in my RMZ 450 thanks guys

I recently sold a 2010 YZ450 with over 120 hours on it. I used Lucas semi 10-40. Never did a top end, valves or a clutch.
I always kept it in the rev's and never a problem. I'm in the process of breaking in my 18 and used Yamalube for the 1st oil change but will be sticking with Lucas as it has been tried and trued
