What kind of oil are you gonna use?

Did my own 500 mile service. I'm gonna run 10w40 Amsoil Full Syn. I've been using it in all of my bikes for years. It quieted down the 109 considerately.

Do you think 10W-40 is heavy enough for a brutish motor like this?

That's what Suzuki reccommends. Who am I to question?

Suzuki also recommends shifting this bike into fifth gear at 31 mph. :

(per the VZR1800 Owner's Manual)

You mean you don't . I think you just voided the warranty ;D.

I didn't go synthetic yet. Was gonna wait until the next oil change at 3000. Already have 4qts. Amsoil 10w-40 waiting.

Ran Amsoil full synthetic in the last bike and had no problems. Will continue with M109.

Just wondering what kind of oil you all plan to use after the brake in period is over?

I drained my dealer oil after 100 miles or so, put Mobil 1 (non-synthetic) in it for now. Will switch to a synthetic after the 600 mile service. But which one?

I was using Mobil1 15W-50 Gold Cap in my last bike, but I don't think it has the correct rating for the M109R.

I changed my first oil at 150 miles and think I will change at 3000 miles to Amsoil 10w40 as well. My other bike never had a problem with amsoil.

Okay... I get the idea that a lot of people here really like Amsoil! ;D

Question: where's a good place to buy it?

I think last time I had it shipped to me. I'll make a post under the maintenance thread in need oil, OK?

K, we beat engine oil to death... what about gear oil....

I dropped mine at er 300 miles (being that most people here aren't used to km) and will drop it again after this weekend at 600 miles... probably going to switch over to synthetic at 1000 miles... anyone else?

I'm getting ready to change my rears oil. And when I change the engine oil over to Amsoil I will change the rears oil to synthetic as well. Just need to find straight 90 weight that meets the specs Suzuki calls for.

Just changed to synthetic oil at 738 miles. I used valvoline [syn power] 20w50. Used a suzuki filter from the dealer, for now. The 20 wt. is only good down to 14 degrees F., but hey. Engine noise has been reduced and I have a much better shift quality. I only rode it about 15 miles after the oil change, but tomorrow I'll get more seat time. 1st gear was its usual double clutch after gassing up with less then a mile on the synthetic oil, but the next stop, 5 or 6 miles later, I blipped the throttle and it fell into gear with no clunk at all . It was as smooth as any bike I've ridden. I used to use amsoil in my 900 kaw's, and will probably switch to it next oil change.

I rode the bike about 20 miles today, till it started to rain, the shift quality is definitely improved. It is normal. Whether it would be as good with 10w40 synthetic, I can't say, as I'm sticking with the 20w50, because I know it worked for me. P.S. 1st to 2nd engagement easy, but still has a more solid sound then the other gears. My 2 cents would be not to wait to long before changing to synthetic.

just ordered...

AMSOIL MCV01 SAE 20W-50 Synthetic Motorcycle Oil: (12) quart bottles
AMSOIL SVGQT SEVERE GEAR 75W-90 Synthetic EP Lubricant: (1) quart bottle (for rears, comin up on 600 miles)

from http://www.amsoil.com/ for 108 bucks shipped.

i live in georgia. warm weather's already here.

Rotella 15W-40W..........non-energy conserving......formulated for diesel engines......this stuff passed the infamous "Shear Test" associated with motorcycle transmission gearing. Our 109's have 10.5 to 1 compression.....diesels have approximately 20 to 1 compression. Diesels create their shear stress at the con rod and crank journal when they fire. This stress surpasses anything a motorcycle motor/transmission will produce.

The issue of what oil to use is ones personal choice, so use what your comfortable with. Just make sure whatever oil you use in NON-ENERGY CONSERVING. Most, if not all 10W-40W motor oils are NEC.....check the round seal on the reverse side of the container to make sure.

i used Mobile-1 15w-50, ran it in my vtx with no problems.... i waited on my 600 mile service to 1000 then switch it has made it a lot quieter and smoother shifting, i also run castrol 75w-90 full synthetic in the final drive
