Several good responses to this issue. I've been running 20-50 Valvoline for
the past 1000 miles in my VStar 650 Classic with no problem, and it's been
hotter than hell in the desert. In particular, there has been no problem
with the clutch, which is I believe what several have termed a "wet clutch."
In that regard, you are specifically warned not to use any sort of oil that
may cause it to malfunction. If anything, I've noted an improvement in the
clutch operation over whatever oil they put in the bike when I bought it,
but of course some of that is because it is broken in better. Part of my
concern is that I began hearing more of the metallic, front end noise ever
since I mounted a windshield on the bike, and with the hotter temps, it
seems to have become more pronounced.
I bought some more Valvoline for the next oil change and will probably
go ahead and use it. If I become dissatisfied with it, I may go with the
Mobil 1, as you suggest. For years, I used Pennzoil in my pickups to good
effect, but two Dodges I own (318 V8s) developed valve problems on it.
Actually, the first truck started going to hell after I was forced to use
Castrol at an oil change on a long trip and the second one deteriorated
strictly on the Pennzoil. Dodge trucks with that engine seem to suffer from
this problem, regardless of how religiously you change the oil, so it may
have had little to do with the type of oil used. I've got a V6 Cougar that
I've been running on the Valvoline and it just blew a head gasket at about
80,000 miles. I'm wondering if switching to a higher viscosity for the
summer may have contributed to that because it was sudden and completely
without warning. As with the Dodge trucks, however, I have learned that
this is common for that engine. Very disappointing. In stark contrast, I
had an old '56 Chevy pickup for about 15 years, which I used to pull a small
trailer and then to carry a camper, running it's 265 V8 engine on Pennzoil,
and she was still running strong and not burning much oil when I finally
sold her after 30 years of excellent service. I guess they don't make 'em
like they used to.
Anyway, thanks to you and the others for the thoughtful input. It is
appreciated.
