Cg125 oil?? Why NOT synthetic?

[19van71]

HI all,

Just read this post (it's old I know), but it recommends NOT using synthetic oil in a CG125. Does this include synthetic oil made for motorcycles?

Thanks in advance

Synthetic oil can have cleaning properties. This can cause leaks in seals and stuff.

A better answer is that its not worth wasting money on it when normal oil works just as well.

use mineral oil until the 6000 mile service, then use a semi synthetic.

You've bought it, so you might as well use it.

Just next time you can use whatever is the absolute cheapest oil you find - I think tesco value 20W50 is under £1/litre. I know their straight weight 40W oil for lawnmowers costs more.

Don't tell potential buyers , but the oil only cost me a fiver anyway

You can oil yourself up with synthetic oil and not get a rash. FACT.

Interesting. I could use that knowledge to adopt a NATO-esque one fuel policy.
Much cheaper than KY, and engines never seem to like it when I give them 4 litres of KY for lubrication.

Hi

Very early synthetics had a low ester content. These cause seals to swell a bit. Without them the seals didn't swell and so could sometimes leak a bit. Not really problem these days.

All the best

Just be aware you could knacker your clutch, a lot of bikes can't take synthetic as it contaminates the clutch plates. Be cheaper to get some semi or mineral and sell the synthetic on than to risk having to payout for new plates and some more oil.

Ignore Keith he's one of THEM.

Synthetic oil was developed by the Taliban and will explode if you get near to important stuff.

That's not a cat, that's your mom when she confused oil of Ulay with synthetic.

So it was your man cream that did that to her? I wondered who had been messing with her grave.

You should beware of synthetic oil!

It can do terrible things to you and your bike. It will not only leak out of your engine faster than you can put it in, but it will also cause your oil filter to clog and implode, dumping debris and dirt into your lubrication system. It also will make every part of your bike permanently slippery because of its linear molecular chain dispersion action.

Then it will leak onto your kickstand causing it to retract automatically, dropping your bike on the ground! But that's not all... Synthetic oil will round off your gears and spin your bearings. It will also splatter onto your seat causing your girlfriend to fall off in the apex of a turn and she'll never ride with you again. Synthetic oil coats your sight window and your timing window with a whitish pro-emulsification additive that is both non-removable and highly corrosive. Synthetic oil will completely leak out onto the ground overnight and your dog will drink it and die.

Synthetic oil will wear out your tires and make your battery leak. It will give you the desperate need to urinate after you put your full leathers on and then jam your zippers shut. It will contaminate your gasoline causing your bike to stall on railroad tracks and accelerate uncontrollably near police cars. It will make it rain during rallies and on weekends. It will lubricate four timing belts causing them to jump teeth and break your valves to bits. Synthetic oil chemically weakens desmodromic valves and causes the clearances to change every six miles. Then it melts the black soles of your riding boots at night before you walk across your new carpeting.

While riding past groups of attractive women it will cause both of your handlebar grips to slip off at the same time so you smash your windscreen with the bridge of your nose. It also causes your swingarm to crack, your studs to break, and your rotors to warp, and then it voids your warranty by changing your odometer reading to 55,555. It also dries out your wetclutch and wets your dryclutch. It makes your clutch slave cylinder seal fail in the heaviest traffic on the hottest day of the year while putting an angry wasp in your helmet for good measure.

Synthetic oil hides your 13mm socket and puts superglue on your earplugs. Synthetic oil will scratch your faceshield and make your gloves shrink two sizes night before trackday. Synthetic oil will steal your neutral and sell it to the Chinese for £1.25.

So let's be careful out there!

You forgot about the backward compression stroke - Synthetic oil will make your bike suck in air through the exhaust, causing a backward compression stroke. This will blow high pressure gases through the carb and up the fuel lines, blowing the filler caps off and spraying all your fuel out the tank and oil out of your engine!
