Red Line 20W60 or 10W60 for an 8V engine?

[Greyo]

I know some 8V Griso owners here use Red Line 10W60 synthetic oil (as I do):

Red Line also makes a 20W60 grade specifically for motorcycles:

For the latter Red Line lists the zinc, phosphorous an molybdenum contents (not so for the former).

Any thoughts/reasons for preferring one over the other?

MG demands a 10W60

I know, but my understanding is that what is really crucial here is the high-temp spec, not so much the cold-temp one... of course, if you were based in Scandinavia or thereabouts it would be a different story...

BTW, history teaches that blindly obeying all of MG "demands" might not always be the best thing to do :whistle:

I don't think you would go wrong with brand or weight. For the record I bought Agip 10w-60. In all fairness I had to mail order oil to get ??w-60 so I just went with Agip.

I am one of the Redline 10W60 users.

Our local Redline store doesn’t carry the 20W60. I won’t hesitate using it if it is available on the shelves and priced like the 10W60.

I use Redline motorcycle oil (10W40) in my other bike and it is more expensive than the 10W60 per quart.

The 20W60 will be less likely to shear in hot weather

If the manfacturer recommends "X" why would you want to use "Y"?

I don't understand this line of thinking!

At the time the 10W60 recommendation came out, that was probably all that was available, and AGIP was about the only maker. As products improve the manufactures don't necessarily rethink their original specification. If the reason for 10W 60, was to have the 60 weight for heat resistance, the 20W60 would be less likely to loose viscosity than the 10W60, and would therefore be more resistant to breakdown when hot.

And, apparently, you didn't even bother to read the other posts above :huh:

Anybody who is familiar with Guzzi bikes knows that blindly obeying all MG recommendations can sometimes lead to rather "unpleasant" results...

Thanks for clarifying the problem John!

Has there been any evidence of engine failure due to oil breakdown?

Not trying to start an argument, just curious.

Mmmh, let me guess... you must be one of those dudes who, in their own mind, are never wrong :mrgreen:

I bought a case of the Agip in 2010 from Refined Performance (RP) Motorsports (great deal too). Time to reorder, but RPM doesn't seem to have a web presence anymore. Any leads on a replacement vendor?

You can buy directly from AGIP USA.

Alternatively, several vendors can be found on eBay.

yee hah, an oil thread, and the insults start on the first page. Classic.

...but I thought we 've already figured out on the other oil thread that the best olive oil is Greek of course! :lol:

...but...dumb question warning...exactly how much do you put in?...My concern is overfilling.....

Less than the specification in the manual. Try to get the oil level half way between the full and add marks. The amount will vary a little from model to model.

Insults? Au contraire, I thought roofus and I had a rather civilized exchange :cheer:

Mmmmh... allright, I'll give you that, as long as you accept that the best wine is Italian :mrgreen:
