Synthetic oil

[oldskool]

Realize I'm in Florida, and it's gonna be upper 80's, mid 90's all summer (HOT). While orienting me to the bike (December) the dealer told me to just run the Honda 10-30 until 600 miles, then to switch to 10-40 for the summer, and then I could switch back to 10-30 for the winter if I wanted, but he strongly recommended I run 10-40 during the summer. I just ordered a case of Castrol Power1, I'm of the opinion it's a perfectly acceptable oil. I do run Amsoil in in all my cars/trucks, and I'm running their small engine oil in my generators, lot splitters, mowers... but I read good things about this oil, so that's what I'm going with.

I live in Florida, 10-40 year round.

I use the manufacturer recommended oil viscosity. I wont argue with the people who engineered and built the product.

Honda have provided a temperature chart for oil viscosity in their common service manual since not every motorcycle is operated in the same climate.

IVE been running 20-50 synth castrol in mine since mid winter, been fine and i don't ride under 30F typically, ever. I have had no issues. Yuminashi recommended it i think as well for the BBK. TBH, its mostly splitting hairs.

10-40 synthetic will provide as good protection as 10-30 conventional and then some. It will provide better protection when the bike is pushed hard as it will resist thermal breakdown at much higher temps. There is only one disadvantage to using the 10-40 synthetic oil cost. That extra $5 a year can be a killer but my bike is worth it

If you buy it by the case it's actually cheaper than buying the conventional Honda oil at my dealer with my "customer" discount... I think there might be another word for that, but I'll keep it to myself.

Trigger warning - The following comments are not backed up by data and are merely supposition.

I've seen oil wars in every MC forum I've been a member of and had an idea: None of the combatants will ever have a problem with their engine due to oil. Dino vs Synth, 30w or 40w, it doesn't matter.
They are fastidiously checking their oil level and researching or sending it off for testing, changing it regularly or even early.
They won't keep the vehicle long enough to measure the .0005" extra wear to some part, or they won't live long enough.
It's the riders (or drivers) who don't know anything about their oil or how to check it that really need help.

And here's the twist ending .
They get interested and learn how to check their oil by reading these Oil Wars threads!
So keep the oil wars going, it may seem like a stretch but I'm almost positive it gets young riders thinking about it and then learning how to change it and keep an eye on the level.
I've had 2 younger guys at work talk to me about oil, (1 bike, 1 truck), because of seeing Oil War threads and now they're all about their oil.

Totally agree . This is the best oil wars post I've ever read . Well done .
