My manual recommends 10w30 or 20w Unfortunately, the same can't be said for the 20w50 from the little info I've dug up so far. So far, the motorcycle feels smoother usually does after any oil changebut particularly noticeable during downshifts. I can live with the possibility of a slightly dulled down top end rush but I just hope the thicker oil doesn't do any kind of damage to the motorcycle because the oil is not as free flowing or getting to all the parts it needs to.
I hear that certain motorcycle engines are very sensitive to oil specs- I'm hoping the 08 R1 is more flexible about that stuff. Andy Wheelie for Safety.
Name Andy. No problem running 20w50 or 10w40, I run them both and use whatever is available. Thanks Andy- I get paranoid about the smallest details when it comes to my motorcycles. I'll report back on the differences compared to 10w40 - supposedly there's a laundry list engine feel, sound, warm up, mileage, horsepower etc.

Motech Mr. Name Steve. So true, little things kill. Lighter oil can improve shifting, make neutral easier to find on stubborn trannies. Outside VVT motors, that's about all I got You're talking to an accountant, my friend Alanrider7 Sportbike Whisperer. The truth is that plain bearing clearances determine what weight oil a motor should have circulating through it.
The bearing clearances have gotten tighter with the increase in horsepower output. Proper oil pressure throughout the whole motor is crucial if you want your amped up sportbike to last. If the oil is too thick, especially when cold, oil pressure drops. Andrew definitely contains nuts. Name Andrew.

Given it's not the warmest country in the world, should I be alright with 15w? Am I correct that the advantage of using 20w50 is less engine wear but longer warm up time? Jan 2, 2. Hi, I use 20w as its easier to come by than the I prefer it on these older engines. You can get away with 15w too. Whichever, you go for, make sure you buy oil specifically for motorbikes. Car oils usually have additives to reduce friction that can make wet clutches slip.
PaulrxsJan 2, Jan 2, 3. Yea it's motorcycle oil. I know I'm over thinking this but I am looking to buy bulk oil to use in the future. I can get Shell mineral 15w40 very cheaply but told engine wear is reduced with 20w Jan 2, 4.
Thats technically correct but dependant on how you ride, mileage, oil change frequency etc etc If you can get it cheap, Id go for the 15wDiscussion in ' Mechanic's Corner ' started by strSep 7, Shamrock Boat Owners' Club.

Messages: 11, Likes Received: Also the major difference in a 10w and the same 10w is the lower the first number is cold start up.
The second number is the running viscosity at operating temp so The higher the torque the hotter the operating temp will be and the older the engine the more wear the higher the second number. Remember to change oil per manufacturers recommendation because plastics are what they add to give the oil a changing viscosity and they break down due to heat and oxygen exposure aka months or X number of hours.
Another factor is how much dirt the oil will suspend in it.
What Is the Difference Between 5W30 & 20W50 Motor Oil?
Synthetics suspend dirt better and longer as well as leave a better film on cylinder walls for cold starts. Sep 17, 4. Messages: 1, Likes Received: Another thing is Chevy vs Ford. Late model Chevy marine engines use roller lifters,they don't care what oil they use. Ford marine engines never used roller lifters they use traditional flat lifters,they require oil with ZDDP, or zinc usually at ppm.
The EPA has lowered the amount of zinc allowed in oil so many if not all gas engine oil has lower than that required for flat tappets about ppm or less. So depending on your engine check your oils MSDS. Sep 17, 5. Messages: 2, Likes Received: That is primarily why I run it.
Also, seems the oil pressure is a little higher at rpm. I've heard being synthetic there is less friction therefore less heat, but I can't prove it beyond the higher oil pressure. Sep 17, 6. Fords, flat tappets and zinc. Perfect sense, but an issue I haven't been exposed to. Regardless of viscosity, if I had a Ford engine, I would be looking at zinc content.
Come to think of it, my last flat tappet Ford, EFI, wiped a cam. Jun 2, 7. Messages: Likes Received: 8. I am new to this forum since i just purchased my first Shamrock this spring. I also have a Ford and been reading about the requirement for Zinc. I first put in Valvoline Racking oil which is high in Zinc.
The weight was 10w I oil pressure when cold was about 45psi and when the engine was run for a while it would drop down to about 15psi.
So I then switched to Valvoline Racing Oil 20w which is on the high end of velocity but it also has high zinc.Jump to content.Mobil super 2000 x1 10W40 vs Mobil super 1000 x1 15W40 cold oil test -24°C
Of course, it's still mineral based either way. Does this make sense with what i am trying to achieve, or it's the other way round? But generally If u can afford use semi syn.

I read an interesting post regarding the use of straight SAE 40 vs 15W40 in 4 stroke engines. Apparently, the use of straight 40 provides better lubrication and wear protection. The only down side would probably be the thickness in the winter time.
Has anyone here ever experimented with straight 40 in their 4 stroke Series 60, N14 or ? If someone could do this and send in an oil analysis to see how your engine wears compared to a 15W40, that would make an interesting comparison. From what I can gather, both oils are 40 weight at operating temperature.
Since it is summer, if someone has done a past oil analysis with 15W40, would you consider running SAE 40 for one oil change and sharing your findings with the forum? Yes, let employers and TruckersReport text me with new opportunities, job alerts and other career information to the number I provided.
There is no charge for this service, but standard message and data rates may apply. Jun 17, 2. It's already been done and proven, in four strokes is the ticket, straight 40 in detroit two strokes. No need to reinvent the wheel at such high cost to the little guy. Jun 17, 3. Thanks for the info, while 15W40 may be the ticket I'm still very curious to see results on paper. I would just be curious to see how fuel economy and wear patterns change. If there is one volunteer out there, that would be awesome.
The only negatives I could see would be increased wear to an engine. I enjoy learning new things, reading others opinions and studying fact. I know you're not arguing and I'm not trying to argue with anyone either, but just stating what my purpose of this post was.
If you know the location of any literature showing wear comparisons in a 4 stroke engine using 15W40 and SAE 40, I would like to see. If you look at the link below, there are pictures show the wear differences to various engine parts on a 2 stroke Detroit. I could NOT find anything showing testing in a 4 stroke engine, which is why I was asking if anyone wanted to volunteer. Testing used 15W40 in one engine and SAE 40 in another. Jun 17, 4. MNdriverJun 17, Jun 17, 5. Why do you need a volunteer?
If you can't find research to explain it, try it yourself. Not trying to start an argument or be derisive; just curious why you'd need someone else to try an experiment for which you want the answer. Knowledge is expensive; you can pay it with sweat and blood, or green cash.
In my opinion: if a manufacturer recommends a specific oil there has been testing done to show that it offers the best performance vs longevity. Friend of mine used to deliver 55 gallon drums of various viscosities of oil to a plant in beacon ny. Inside they had about engines from various manufacturers, all running at full tiltI live in a hot climate Middle East.
Winter temperatures between 11C to 22C 52F to 72F. Many people say, you should use 20W50 because owner's manual recommend 5W30 for cars in Europe, American not in Middle East. Other people say " use whatever weight of oil the owner's manual recommends; the manufacturer knows what's best for each vehicle it produces ".
Ok this is how oil viscosity works. Your first number 0, 5, 10, 15 says how easily an oil pours at freezing. A 0 pours easier than a 5, a 5 pours easier than a 10, a 10 pours easier than a So the colder the climate the lower your want the first number because it will get to parts quicker. Your second number 20, 30, 40 tells 2 things. How much pounding force it can take before it spreads out completely and how hot the temperature can get before the oil thins out beyond its working viscosity.
SInce you live in such a warm climate where it doesn't get below freezing but temperatures are excessively high, I would recommend 15w But before you do that call the manufacturer and ask them their opinion because they may tell you you can't use anything else but specific oils they recommend.
This is only my opinion based on my knowledge of the automotive field. I will tell you though I drive a cadillac deville it says 5w but I use 0w synthetic in the winter and 5w synthetic in the summer.
Use 5W Oil viscosity is determined by bearing clearance and modern vehicles use. To get proper lubrication to those bearings requires a thin oil like 5W That is why 20W is for older cars. In those days the mantra for engine lubrication was "pressure;" since then it is "flow. Outside temperature has little to do with oil viscosity although very cold temperatures require a low pour point at start-up because the temperature inside the engine is about the same regardless what it is in the engine compartment.
Other than that, either 5w or 10w will work just fine for any temperature. Only difference between the two is cold flow ability, 10 will move slower on cold startups vs.Click here to learn more.

Last edited: Apr 9, Messages: 2, Anyone know what the advantage of heavy cold temp oil in this app be? TrainingWheelsApr 9, Messages: I had sent a message to hydro gear about this subject about a month ago.
They said they recommend 20w I have been to the hydro gear school as well as rebuild them just as often as we replace them. Some customers want synthetic in their units, some just run the cheap stuff. I do have to say that we have seen no advantage to running synthetic in the hydro gear units. The reason you can't run conventional oil in the parker units because they have a lower capacity and they run hotter so the oil will burn. Have had to rebuild several parker units because the customer burned them up by just using regular oil.
In my personal exmark since I get oil at cost, I run motul v 15w50 in my trannys and engine.
It runs silky smooth and the engine uses very very little oil between service. Here in texas it gets friggin hot. Just for the heck of it, I shot a infra red on my oil filter when I was runNing it hard, oil filter was degrees. If it gives you the warm and fuzzies, put synthetic in it, but in the hydro gear units don't need it.
