Oil Cooler [?!?]
 

Hi there my friends, In italy Summer is arrived, and I am concerned about Engine's health.

Looking around on the net i saw this interesting Item too cool the oil of engine.
Has anyone ever mounted it?

How would you hook it up without drilling through the case?

I think you are overthinking the heat issue. The GZ will operate quite well in hot areas. I would suggest using an oil with a 15-40 or 20-50 weight and call it a day.
I'm sure the oil cooler could be used and plumbed in but it is likely not needed.

The gold colored cap behind the letters "QX" will replace the cover of the oil filter housing.
Looks like it works with the pressure difference across the oil filter, such that a part of the oil will not get filtered, but cooled instead.

Cool gadget. But, utterly unnecessary.

With disadvantages outnumbering the advantages, if any:
- it needs oil to fill, the oil level in the engine will be lower
- not all oil gets filtered
- crud from the filter may re-enter the oil stream via the cooler
- in the winter, your engine takes longer to heat up and may not run hot enough
- more weight
- more parts to fail

this was an alternative option to make the oil pump pressure makes oil go through the radiator and then in the carter..what do you think?
I am thinkin of this because, in Sicily, we reach 36/38°C (about 100°F, or 300K) and the bike should carry me my belly, and my girlfriend round the MOUNTAINOUS sicily

Tenerife is also hilly (Giant volcano, right in the middle) and gets very hot in summer. Never had any overheating problems, even when riding two up. :tup:

If you anyone does install one of these, please be aware that your total oil capacity is also going to increase so you will need to determine your new oil fill capacity based on the size of the oil cooler.

That being said, I agree that it's most likely not necessary. But they are pretty cool and can offer peace of mind to those who worry too much.

for now, i just changed Air filter, that was pretty old, and engine breath pretty well now, i will decide later if upgrade this oil cooler or not =)

run a stout oil (15w-40, 20w-40, 15w-50, 20w-50); the bike is designed to bump up idle speed when warm (higher rpm's flows more oil thru the motor to transfer heat out of the combustion chamber) when stopped (in neutral or clutch pulled in)...this helps cool the engine when bike isn't moving

10w-40 is the factory recommend oil and 10w-40, of all the common oils, is a weight that is designed to handle the broadest range of heat variance in the world.

We do not recommend anything higher than a 15w-40. The flow rate and tolerances inside the GZ engine need something that will actually mate and lubricate. Cooling is accomplished through the fins, obviously, and the metal combinations found in the head.

If heat exchange is a real concern of yours, simply increase your main jet one size, enriching your mixture and running cooler - Do not leave your bike idling for any extended period of time - and just ride.

Simple and to the point. No extra plumbing for oil lines and potential future problems. Best of all it is cheap and easy......................like some of the gals in my past. :hehe:

A cool engine is an engine with a long life.

Not very many of you live south of my latitude. * not that I hold it against yah * 9~)

I'm thinking 20w50........It's hot around here.
And an oil cooler would be very.... well... cool...

I want i want

I would be a little leary of a 20-50 oil. The oil pump may not pick up a thicker oil when first starting the engine. Initial start up is the most critical time for any engine. Rotella 15-40 will likely work well and is designed to live in really hard working work engines in big trucks.
Keep in mind the GZ is used in many other countries where temps reach much higher than Texas and somehow survive.
Or just change oil a bit more often to prevent oil break down from heat. Always keep the oil topped up as it is used to carry away heat internally.

Welp. My 2000 suzuki gz250 owners manual does list 20w-50 as one of many viable options for warmer climates.
So now I'm curious...
Has anyone put 20w-50 in their bike and had the pump fail?? In a warm climate?
A weakness suzuki didn't know about?

I should have explained better. It is not so much a pump failure as a thicker oil not being picked up right away as soon as the engine starts turning over. If the manual says 20-50 oil will work then who am I to argue with Suzuki engineers who determine the specs and engine management. By all means go with the 20-50.

I have been thinking of going with a 20/50 oil as well as the temps here in Vegas have been consistently over 109 to 113 degrees the past two weeks. I guess I should check the manual for my own peace of mind. Great discussion.

15-40 is as high as I would go.

over 15w-40 is a waste of gas and lost of power because the oil pump use more power from the engine to move the oil.
this is why the new cars move to 5w-20 ore 0w-20

Welp. I got a long log of gas mileages that I've been keeping since I got this bike ten weeks ago.
I'm on my second oil change now and I have two of my three oil filter multipack left too.
(I'm changing often to clean out the engine.)
Imma look for some legit 20/50 motorcycle oil and switch filters again in 2 weeks to a month,
new filter and all, then compare any changes in the gas mileage log after that point.

My prediction is the mileage will be practically unchanged and the benefit to the engine in
a hot Texas summer is obvious as the owners manual acknowledges.

However. I will be honest. If my mileage drops or if I blow up my oil pump I'll report so.

Ah! Here we go. I've heard good things about Chapparal so I'll order a couple quarts of http://www.chaparral-racing.com/Prod...2ZMaAu3X8P8HAQ

Sounds like a plan. You should keep an eye on the oil level until you are confident in the oil usage if any. Of course just checking the oil on a regular basis is highly recommended. A quick glance at the oil window is a good habit to get into everyday that you ride. Yeah, I sound a bit paranoid don't I ?

I am ocd checking stuff all the time too so no problem at all.
So far haven't had to add oil between changes... Brief as they are.

I am putting this at moment; i usually ride Highway, 60-65mph, and i found it much better than 10w40 or 15w50 i used before.
Here in sicily temps are very high bout, 27°C to 35°C at moment, and it will rise in august.
Yes, I'm still reading and reading about oil cooler, and looking for someone who just did it to see how.

Motul is a good product from my experience. Used it in a dirt bike under very hot temps. Even after 3 or 4 hours of riding the tranny still shifted and felt perfect. That in itself told me there was no oil breakdown. My riding buddy used real cheap oil and had a heck of a time. He would almost have to jump on the shifter to get it into 1st gear after we would stop for a scenic view. I on the other hand really annoyed him by reaching down and finding 1st gear with a finger tip.

i was using 20w-50 for past few years....and my engine just work fine...no fail pump at all

and yeahh...motul esther 5100 is a great product for sure....but very expensive (IMHO)

and i was using oil cooler from suzuki SV650 since 2 years ago...

Oh goody!! Some one who did an oil cooler mod. We have been waiting for you. Please do a full write up and pics of the installation.

its not someone dude....many of my friends here did oil cooler mod too...with few various different ways

here's the sample (i get in from google)

GIZZZ :wtf:

Yes! i see two variants. I want details 8~D
The oil cooler tempts me.
It tempts me, and I shall have it. I'll chase it round the Moons of Nibia and round the Antares Maelstrom and round Perdition's flames before I give it up!

Actually there is 3rd version...i"ll post it later
