I do act like that mainly because I have a lot of knowledge on a wide range of subjects. The more knowledge you have on a subject the easier life can be. Though ignorance is bliss in some cases. With my tdi I always add hot shots diesel oil and fuel additive as this is a must with diesels, keeps injectors clean all oil passages clear including stock and aftermarket oil coolers, it also believe it coats the walls with a corrosion inhibitor I'll have to read their page again. Added about an ounce to the last oil change I did to the bike about 2 months ago and put almost 1K miles on the bike since and had no issues with the clutch could be the friction inhibitor the royal purple oil I use has or could be the fact that the additive doesnt cause issues with the internal clutch on my specific bike. I dont recommend washers because they literally serve no purpose IMO. If you torque the bolt to the right spec and ensure the threads are not stripped or warn out then you wont have a leak no bolt properly installed will ever leak or shift during operation. I was trained this way when I went through tech school. Oil additives will not destroy an engine in fact it will aid in the purpose of the oil. The only additive that will definitely destroy an engine is a stop leak fluid as this would expand the seals causing them to over expand and break especially if they are old and near cracking range.On the one hand u act like u know everything, but then you recommend not to use washers (which is ) to use diesel additives (??), and behave quite ignorant. I think you read the wrong the wrong books.
The manual most likely references climate for those random days where it will drop below 40 then be higher later in the day or the next day ie the past few weeks in NJ. But I would think they would give that information as an ambient due to seasonal change for those who ride I wouldn't think anyone who lived or lives in an area that's been at or below 40 for over 30 years would own a motorcycle and if they do they got bigger nuggets then anyone. Granted I ride when its 40 or below especially if my daily's dont start or hung up waiting for parts and I need to get to work or want to have some fun with my girl.Perhaps you did go too scientific for me (just kidding) however ambient temperature and climate are 2 different things. Your manual has an asterisk next to the spark plug heat recommendation and that may be confusing you. Underneath it states "Cold Weather Climate 5C". Climate is a long term average temperature over a specific period ie 30 years. I tried various cities and ended up with Juneau Alaska climate average 4.8C . My climate in Vancouver is 11C
1. Those tests were both synthetics as compared to your statement of synth vs conventional. Not quite a lab test. If you want to look at an oil that may run down a tube faster look at the oil PDS for pour point. If you really want an oil that reaches parts quickly at cold temp use a 0W. Personally I stick with 10W40
2. Additives: I quoted Chevron because you use their products. Are you going to provide any facts that conventional oil contains no additives?
3. Spark plug heat range: Ambient temperature and climate are not the same.
4. Magnetic drain plug: I don't think mine is.
5. Drain Plug Sealing washer: "I've never owned any vehicle or motorcycle that's used a sealing washer." I don't know your model so maybe true. Partzilla is good for a parts cross reference in case your manual is inaccurate.
Oh yes the more it will help the more I like it lol. Dont shop in person I'm an online guy cause I'm the laziest person on earth. My uncle and grandfather love addtives so I probably get it from them but when I went through tech school I was told never to use the washers as they cause more issues then their intended for. As long as you tighten it to spec and ensure threads are clean and aren't warn then you'll be fine. Only once had a plug leak but that's because the PO of the car it had an issue with prob never did an oil change in his life and the threads were crossed. Though it is preference for the washer I've never had one in a manual tell me to use them but again I've never used a manual to do an oil change just second nature for me. Never had a car or bike that had it on from stock.Dude! You sure like using additives don't you. It makes no sense (to me) how you would recommend putting additives in everything, yet be disdainful of using a 30 cent washer whe pretty much every manufacturers service manual calls for one. To each his own though, just doesn't make sense to me, but hey... someone has to buy all those additives on the shelf.
Again, you don't understand the point:Btw dont tell me how to act when you legit cursed in your own emoji way. Dont be a hypocrite.
