SF, SG and SJ oils

Hello All

I've got a GSX-R1000 (2001 model). I'm noticing that it's
really hard to get API SF/SG oil now days... as these
standards are now obsolete/superceded.

For example, the the primary oil brand at one bike
shop in Adelaide is Mobil 1 SuperSyn (which is API SJ).
The salesmen told me that this oil supercedes SG and SH
and perfectly fine to run in my bike.

I've had a quick look on the net. It's a confusing
mess. I did come across one API spec page that loosely
said that SJ replaces SH, and SH replaces SG.

What's other peoples opinion ?

Is it safe to use API SJ oil in a 2001 gsxr ?


cheers

head to Kmart/BigW and you will find SF/SG oils

IIRC BMW said never use SJ , warranty void if found

what brand were you using before ?

 

What sort of oil do you think they are using in all the racing bikes these
days? The motors in Suzi's at least, are merely built on the base motor as
found in your bike, and they are made to perform in a manner is unliely to.
You said it all in your introduction.

Err on one of recent telecasts,team boss [wsbk]said the oil they use cost
$2000 a race.Suggest there must be some difference.Hugh

 

On a Jaguar forum I frequent, it's been discussed a lot.
The feeling is that the newer classifications are manufactured for
newer engines with roller cams, cams acting directly on valves etc.
These newer formulations are way down on additives such as zinc, which
is an anti scuff agent, reducing wear in high pressure/load areas.
It probably doesn't matter on a motorbike engine, with overhead cams
etc, but it may.
I've found teh older formulations have yet to be changed. Like the
original Castrol GTX.

Hmmm? firstly pardon the bad copy in my previous post; seem to be making a
bit of a habit of it lately?
As well as that misdemeanor, my reference (unexplained)
was more directed at the average punter racing around our Aus. tracks.
I suppose in that regard, their demand for engine longevity differs from
that of the road rider. Ah well!

race motors dont run oils for very long the aplication is diferent to road
use !!

The issue with motor cycle oils is the fact that most use engine oil in gear
box that breaks oils down quicker

The issue with motor cycle oils is the fact that most use engine oil in gear
box that breaks oils down quicker more so with thicker additives with long
molcules !

Thank you all for your responses. It has cleared the
confusion.

Cheers.
