Shell Rotella T all the way Bay-beeee!+1 Shell Rotella T6 5W40.
I'd only run 10--30 in winter in the north....
OK....just wondering how the masses feel about this engine oil weight.
Not that i have used it, yet, but I found a very nice semi-synthetic high mileage blend at the local autozone. Hey Baby is 11 yrs in and has a little over 83k on her. I have screened the last 5 oil changes and have not found anything at all as far as shavings or debris.
Those oil changes cover almost the last 20k miles. I know Mama Kaw doesn't recommend it, any ideas on this considering the age ang state of my motor. Inquiring minds would like to know.
Stay cool this weekend, and ride safe.

Why would you do that? You gain absolutely nothing and in fact lose the viscosity modifiers that help hold your oil to a higher weight when hot. Your 10W30 starts as a 10 weight and has viscosity modifiers added to make the oil "think" or behave as though it were a 30 weight oil when hot whereas a 10W40 starts as the same 10 weight oil and has more viscosity modifiers added than the 30 weight oil does so that this oil "thinks" or behaves as a 40 weight oil when hot. Please keep in mind that is is these viscosity modifiers that we need extra of in our oils as the meshing of the gears in our transmissions is what "chops" up the viscosity modifiers breaks down the oil and makes the bike shift poorly. Viscosity Modifiers are like long curly strands in our oil that when cold are pulled up nice and tight to keep the oil thin enough to flow when cold but yet uncoil and expand when hot and this is what keeps the oil from being as thin as water when hot.
Stick to what the factory calls for..... Myself I run a Mobil One 15W50 year round and yes I live in MI.... Better living through modern chemistry!
Mobil 15W 50? The text on bottle now states uses zinc to conserve energy. Thought zinc modifiers were bad for bikes?
The API ROUNDEL does NOT say "Energy Conserving".
Use Mobil 1 10W 40 4T MotorCycle.
Up til now considered 15W 50 a good alternative?!

Question:
What's the Zinc Level Mobil 1 15W-50?
Hello, I read your answer about ZDDP and phosphorus levels. You even list the phosphorus level in your table, but you show no listing for the level of zinc. Other oil companies also list their zinc level. I would like to know the zinc content in your 15W-50 oil. I would like the level for the gold cap and the silver cap separately. I drive a car that is over 20 years old and the answer is important to me. Thank you, Jerry

Answer:
The important element here is the phosphorus since it is the active antiwear additive. That's why we show phosphorus as well as zinc. The zinc content is in the range of 0.12 - 0.13 weight percent (1200 - 1300 ppm). (Mobil 1 Extended Performance 15W-50 [gold cap] was discontinued about May 2009.)
