Troll?? What the hell is that suppose to mean?Suncoast said:Hmmmmm sniff sniff I think I smell a TROLL!!
It means I think you are just trying to stir up controversy by sticking to your 50wt oil arguement, which totally flies in the face of all reasonable and accepted practices. You haven't brought any valid arguements to back up your views. You are just looking for a disagreements in this thread "trollish" behaviour. No offense but there have been engineers on this site that have stated why a good 10W60 oil is needed. I suggest you do a search of the past oil threads and then see if you still stick to your arguement. just sayin!!!bobbymoto71 said:Troll??

I'm still on the fence on how to respond to your comment. But until then, please go back to my original post and read the last two sentences. Take a minute and think about my intent before you start throwing out slanderous remarks.Suncoast said:Hmmmmm sniff sniff I think I smell a TROLL!!
It's a 2 valve motor 2007 norge. Where I live doesn't get below 30F and gets into high 90F and low100F in the months to comeGuzziMoto said:First question is whether the OP has an 8 valve or a 2 valve. It has been stated by some pretty knowledgeable folks that the 8 valve motor really needs a good quality oil of the right specs. Whether that means 10/60 or not...... I don't have an 8 valve so I can't say I care. But some of those same folks have also said that the older 2 valve motor is not that particular about the oil it uses. The two motors have vastly different designs and as such vastly different oil requirements.
So, until I hear which motor he is talking about I am going to reserve judgement.

For a 2 valve motor I personally don't use 10/60. I would not use a straight weight oil, at start up it tends not to flow well. And as they say, most of your engine wear happens at start up. I did play with straight weight oils in a Harley motor, but in the end I went back to multi-weight oil.bobbymoto71 said:It's a 2 valve motor 2007 norge.

john zibell said:Not only is oil to keep metal surfaces separated, it also functions to cool the plain bearings. A thinner oil will flow faster resulting in improved cooling of the bearing. So long the viscosity is thick enough to keep the metal apart, and thin enough for a good flow rate for cooling is the viscosity you are looking for. As far as what that viscosity is for the different Guzzi engines, I wish I had more information.

So, can I ask a possibly related question about cooling? I've read somewhere (possibly here on GT) that fuel also acts a a cooling medium. Engines which run lean tend to run hotter. Enrichening the fueling mixture (say on a FI bike because I don't know about carburated engines much) will lower the engine temperature. Will this action also put less stress on the oil and therefore one can have a greater range of oil viscosities, and therefore brands, from which to choose? Just asking.Luma46 said:The cooling function of the oil is actually very good point that John has raised. And for that reason and for high viscosity at cold temperatures (and yes Canada IS rather cold) I am very cautious selecting the heaviest grade oils like the 10W60 no matter what the "hot bloodied and hot weathered" Guzzi manual says.
