switching to synthetic after 16k on dino

[East Coast]

I want to switch to rotella synthetic. So I need to use a semi-syn first? I frequently submerge my bike. Will synthetic oil absorb water as well? I want it to absorb water so when I do an oil change the water that entered will flush out. Same with metal particles, I have heard that dino oil does a much better job at absorbing metal so when you do an OC it all drains out. I want to extend my OC interval and i am very hard on my drz sometimes running it for 22 hours straight at 70mph.

You don`t need to run semi synth.....then synth. Go straight to synthetic. I would not switch to synthetic to gain longer OC interval. Specially if you are running long at 70mph. The gearbox beat the snot out of the polymers, and even break down the oil more. If you want it to last......Try to do the OC every 1000 miles...give and take a few.?

so you think that synthetic will break down faster with this sheering gearbox?

[GOF1]

No. He knows that the oci should not be more than 1000 miles for a DRz using quality oil.

Do you think using syn will make the sludge in my engine loosen up? The sludge could then plug my oil passages, such as crank journal passages, and will seize the crank bearings. If it aint broke dont fix it, I would hate to have a problem switching over. If you mix synthetic geese with normal you get sludge, wouldn't it be similar with oil?

i thought if you mix synthetic geese with normal you get a duck.

No..... quite the opposite:thumbsup:

If you have sludge in there now.... You are going too long between OC.

You can switch back and forth either way anytime. You should not have any sludge in your engine unless you have been very lax in your maintenance. All oils have detergents. Synthetics have less because they naturally have more solvent properties. Rotella T synthetic is good oil. I use it in many of my machines.

For the DRZ400, I recommend a better grade of real synthetic. Many threads on oil here so I'm not going to go into it further.

The sludge that forms mixing different types of grease and lubes is a different question. As long as you are mixing engine oils, it is not a problem.

No, you get Canada Geese.

[MRCPOPE]

His sludge could be the parafins left behind by using automotive oils. Use a good synthetic and change every 1000 mi. I use Rotella T in my DRZ with no issues. I figured the sheer resistance of the Rotella can't hurt, and it is the oil Suzuki has its name on.

last time I checked it was clean as a whistle. Does synthetic absorb water as well? When you change the oil do clutch particles flush out as well? these are the two minuses for me to switch to a syn.

None of them will absorb water..... They might slush it and somewhat transport it....but chemically will not absorb it.

Either will transport clutch particles....and other particles for that matter....?

awesome just the answer I was looking for. I am switching next change.

engines are broken in with dyno oil for the seals right? That would make sense. I read somewhere that syn oil increases slude deposits because the crap doesnt get absorbed in the oil, damn people with their untested opinions.

Synthetic oils are too slippery for rings to break in right. There are a few bikes that comes with synt. from new. A friend of mine bought a ktm 950sm. After 1500 miles...he found that it was smoking a little, and were using oil...... He put mineral in it.....let`er rip for a 100 miles..........oil consumption stopped along with the smoking...... Go figure.....?

No type of oil will make up for abuse.

His rings were already set by 1500 miles.

that was just a general question dont pee yourself man. merry christmas.
