What type of oil to use?

[balou34]

Hello everyone, I was just wondering if there is a type/brand of oil I should use in my hawk for optimum result?

It would be for street use only, no racing(yet anyway). The bike as 18000km on it and I'm reluctant in going with synthetic since I have no idea what is in it right now.

Thanks

I know mobil 1 is a synthetic, but i will prolly be putting mobil 1 10W/40 in my bike next oil change..
From what I have read around online and on hawkgt.com people seem very happy with the 10w/40 mobil 1 and the 15w/50 mobil 1..I will check it out next time..
My last oil change was just random cheap stuff, from what i remember.

I have heard lots of great things about synthetics and synblends. They are supposed to be great at holding their viscosity over a large range of temperatures that conventional oil just can't do.

There is interesting info in that article, anyway I have a better idea now what to use.

Thank you

If you can, call the previous owner back an ask him. But if you can't I would go with mineral oil because if you service your engine with syntetic now, there a chance that you are going to dilodge carbon in the engine since the syntetic oil is more detergent than mineral oil.

And good luck with the Hawk.

I've been using a synthetic blend since day one (8/21/1989) in my 88 model.

Sorry, my comment wasn't very clear. If the engine was running on mineral oil since the begining, I would stay with mineral. On the other hand, synthetic oil are better since they withstand more heat before braking down.

Feel free to correct me if I'm wrong.

While synthetics in theory are better at keeping the engines clean. If the motor has been somewhat regulary serviced through it's life you'll have no problems switching over to synthetic. We've done it on hundreds of 100,000+ mile cars at my old shop with no problems whatsoever.

As of now I'm not running synthetic in my Hawk as it seemed to make the clutch a little sloppy feeling, and it's going out anyway. But then that was auto synthetic, the additives for motorcycles with wet clutched vary. Delo 15w40 is what my Hawk sees with filter/oil about every 2000ish.

Re: What type of oil to use?

Hello, new to this forum but I thought I would give my two cents worth.

I recently Aquired a GT, believe it or not, the original bike I learned to ride on. NOT the same model the same VIN became available so I scooped it up. $800 from a good friend, it has 7000 original miles on it.

I changed the oil right off as it had been sitting for 3 years, I changed it again after 500-750 miles to AMSOIL the 20/50 weight for clutches, NOT the harley stuff. I have seen an increase in mileage 3-5 mile per gallon (as much as 120 from a tankful) as well as better idling and shifting especially. I'm a mechanic and have been using AMSOIL for 3 years, I think it improves the way the motor runs, also makes the harley motors (no cooling systems) run 10-20 degrees cooler just from changing the oil. So, might want to check into that.

Additionally, it reduced the reduced the valve ticking that seems to be present in many of these motors. Hope this helps. Smoke' em in the corners thats where this bike really shines.

no molley....

I don't know what it is or how to spell it, But I have been told you can use any engine oil as long as it does not contain an ingredient called "molley".Molley will cause the clutch to slip.....I'm not sure about the synthetics.....But NO molley!
