How often do you need to change oil? Also what about synthetic maxima compared to rotella 15-40 convential what is your opinions?
I would like not to spend $16 an oil change with maxima but the synthetic oil gives you more power and runs smoother. I heard there is nothing wrong with running a mobile 1 delvac synthetic or rotella conventional either. PLEASE COMMMENT!

What kind of machine are you putting this oil in? It would be helpful to know. I get the gallon containers of Maxima 15W50 full synthetic and I think its worth the money but you will find a huge gamut of opinions of what people like to run in their bikes on Thumpertalk. I like to run a full ester synthetic personally but there are many fine oils out there. I used to run Golden Spectro synthetic blend and would not hesitate to put it in one of my bikes.
Just make sure your oil is labeled as O.K. for motorcycle use-JASO MA if you run it in a bike that shares engine oil with the transmission(this is so your clutch won't slip) and JASO MB in bikes such as the Honda CRF450 which has separate oil for engine and trannny. You would then run the friction modified MB in the engine and the JASO MA in the transmission in a bike such as the CRF450.
As far as changing oil-depends on if its dino oil,synthetic blend or full synthetic with full synthetic lasting longest. Pretty safe to stay with what the manual recommends as far as hours or mileage but I change mine about every 750 miles on my dualsport and about 4- 5 major rides on my dirtbike all subject to conditions encountered. Probably too often but I have gotten a lot of miles out of the bikes and still have good compression.

Not one of these again.

I think you need to do research before you post something like this. This topic has been beat to death. And if synthetic oil makes your bike run smoother and give you more power that is news to me.

Synthetic all the way!!!! Adds a solid 20hp to the bike, and since yours is a 2012 yz450 maybe even more. How much power you'll get depends on how your carb is set-up on that bike, and what position you have your gongilator plate in.

I've never seen an oil-related failure in a bike that was serviced at the correct intervals. Run whatever you want.

Use the recommended oil weight that is listed in your manual. Pretty simple. I like to run Vavoline 4stroke motorcycle oil.

If I were to give a recommendation which covered all bikes, in all temperature ranges, I would say to change your oil every 2 rides, and put rotella 15W40 into it.

I also am a supporter of the change it early and change it often as opposed to worrying overly about what brand. I run rotella as well. If I could find a comparable priced in a gallon I would consider it but rotella for the price is hard to beat.

I have an 11 yz450 and I run the spectro blue cap( think its the regular non synthetic) and change oil and filter once its black its a good rule if thumb. About 1-2 hrs of ride time. I probably change it way more than needed but its good piece of mind and using the regular oil it's a little cheaper.

Another vote for the Shell Rotella. I run the 15-40 in my XR400 (which is basically a tractor....nothing like your bike which is a high performance machine). Just follow what your manual says and you'll be fine.

I run Chevron 10-40 non energy conserving in my FZ1 and Rotella full synth in my track bike. 30,000 miles on the FZ1 with no problems and about 10,000 race track miles on the gsxr. I picked up the XR in a trade not even knowing the maint history....all three bikes run great.

Numerous oil threads on every motorcycle forum. The bottom line: change it regularly and run whatever oil gives you piece of mind.

Me either. The only thing I've seen is some clutch slippage with certain oils in certain bikes.

I run Amsoil 10w40 Motorcycle oil in my 2006. Changed every 2-3 hours.

Bike has 300+ hours with no issues and no valve adjustments. I race 450B and 35+ also some trail riding.

I was running Mobile 1 Racing 4t 10w40, but my Rekluse EXP would slip a little under heavy load. Rekluse recommended going to Rotella T 15w40. It no longer slips, but I do change the oil more often than I would with the Mobile 1. Rotella T and T6 are both JASO-MA compliant. One of the most important issues when dealing with motorcycle oil is the shear stability. Motorcycle transmissions are very hard on oil, and can shear a 40 weight into a 30 weight pretty quickly. Motorcycle specific oil is usually blended to help shear stability. Some HD Diesel injectors are also hard on oil as far as shear stability. This is why HD diesel oils can make a good alternative.

I run Mobil1 Racing 4T in my Rekluse Z-Start Pro equipped '06, and I have no clutch problems with it. No problems with Amsoil MCF, either. Both of these oils are JASO MA/MA2 compliant, also.

Diesel injectors are not generally lubricated by engine oil (the fuel does that), so it has nothing to do with the matter. Rotella, point of fact, was one of the weakest popular oils used in YZF's for a long time until it was upgraded. It would fall out of grade within 2 hours time in a YZ250F (by actual oil analysis) and failed the standard ASTM D-6278 viscosity shear stability test (done with diesel injectors, interestingly) miserably. The current info I have is that both Rotellas have now been improved in this regard, but the point is that just being a Diesel ("C", or Commercial grade) oil means nothing at all.

Many Diesels, including the Ford 6.0L have HEUI (Hydraulic Electronic Unit Injector). This uses high pressure oil, and is also what shears down the oil in these engines.

My clutch does slip with Mobile 1, and it does not with Rotella T, that is fact.
