I like the sound of the Mobil 1 MX4T oil, but...

The notes say that most bikes don't have catalytic converters, and as such they put more phosphorous in the oil for blah blah blah reason.

So, whats the dealio? Would this f*ck up the catalyst? I am not a greenie or anything, but I would prefer not to destroy this component if I can help it.

TIA!

WC (or any one of the many knowledgeable people on this forum) I have read a couple of times over the years that motorcycle specific oils had additives specifically designed to help reduce shear breakdown from the gears in the transmission. The first time I read this was an article on oil in Rider Magazine. Have you heard this before, or do you think it is bunk? I would think the bike manufacturers are BS'ing me to sell oil at an inflated price, but the article's have been in bike magazines (I know supported by advertising dollars from the bike manufactures). It seems like most posting preferences are for automobile oils. Have I been dupped?

 
Instead of the gold cap 15w-50, has anyone used the silver cap 0w-40? It's factory spec from the likes of Mercedes and Aston Martin and doesn't say "Energy Conserving" in the SAE label, although the data sheet sort of implies that it is. Target had it for about $5 a quart.

Mobil 1 0w-40 Silver Cap

I just noticed too that there's a Gold Cap 10w-40 although I've never seen that in the store anywhere.

One nice thing about the fancy Euro MC oils though, you can get them in a single 4 liter jug. Perfect for the Feej, no fuss and no leftovers.

Cheers,

Jim

Well if you want to change to synthetic you better be aware of the dangers that this move brings with it.

Read the following report and decide for yourself if you still want to do this or not.:der:

**************************************************************

Beware of synthetic oil, it can do terrible things to you and your beloved motorcycle. 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 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 right 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 stole your neutral and sold it to the Chinese for $1.25.

Synthetic oil will make you grow a tail.

Synthetic oil will write long crazy e-mails to your Internet friends and then sign your name at the bottom!

LMAO!! Very good, thanks fer the laff. :clap: :clap: :clap:

My answer to the question: 4,000 miles, Mobil 1 Red Cap til I run out. And now that I know the Gold doesn't have friction modifiers, it's next.

FNG :)

 
Do what you feel is right or your bikes tell you is right, cause I don't think there is a wrong.

I changed my oil at 40 miles to Shell Rottela T on the FJR1300 and have been running it happily for 13000 miles. On the wife's cruiser, it did not shift as well with the 5-40, so I changed it to Mobil 1 15-50.

Of all the things to worry about, I don't worry about oil. I have bought the argument that synthetics are better than non synthetics so I use them.
