Motul 7100 4T Synthetic Engine Oil

[BigDave in PA]

I service my sister in law's Breva 750 every year. I have been using Motul 7100 4T 10w60 Synthetic Engine Oil in the past and it has always had an SG rating. The 4 liter jug I got today is rated SN. I'm afraid to use this in a flat tappet engine. Is there a suitable additive to use or should I return it and shop for a different brand oil? This has the same part number as the previous jugs that I have used but the rating is now different.

I
I noticed that the 2000 vassal manual said 4T but  not SG.   Are  you sure you need  SG?   I'm not trying to argue against the recommended spec,  just asking if you're sure you need it.

I use this in oils that are not SG rated---

I'll look st the owner's manual. If it calls for an sg rating I will definitely not use this oil.

Thank you. I think the local pep boys stocks one of those.

Motul 7100 4T oil IS rated SN

HOWEVER, it claims it is SG REVERSABLE

so you are fine there.

now lets not turn this into another oil thread :P :D

That data sheet is 5yrs old but if it has changed they would have a newer one on record. Never had a problem yet using that oil, even on 8V flatties.

Ya, I realized after I posted

But I did get that off their official site...so...you think they would update it...? *shrug*

Dave,

As you know (since we're brothers), I've been using Motul 7100 4T in my Cali 1400. I just looked a quart bottle that I have on the shelf and it says "APA SJ/SL/SM/SN*" The asterisk statement below says, "Backwardly compatible with previous API Service Categories"

If the contents haven't changed it's still good.

Hey, a new name for old guys----- Backwardly, I like Reversable better.

Why not just use the Guzzi specific SG rated ENI i-ride 10W60, it's loaded with zinc and phosphorous perfect for flat tappet motors. 

If the bike can take 15W50 then Mobil 1 15W50 contains 1300 ppm zinc and 1200 ppm phosphorous (see pg 3 in this pdf):

Don't mean to get off-topic but I have to ask if it's a good idea to use same Motul oil in 10/40 in my Cali 1100i, as specified in my owners manual?

I checked and this is maked sn and says nothing about back compatible.

[Chuck in Indiana]

Weird. I looked on my remaining jug, and it says SG SJ SL SM SN..
All I know is it smells a nice..

Well, let me explain this to you and I'll make it simple so that you can understand. It's my sister in law's bike. She's had it for a couple years and had a 4 liter container of the motul 10w60 sg rated that is almost used up. Before I ordered the exact same oil I checked with several venders and it was listed as sg. When it arrived i noticed it is now listed sn.
I really expected more of this type of response and it's the reason I rarely post here.

I  don't think anybody was trying to be a jerk but I've been wrong before.   However as the years go by oil's improve and the lettering  changes to reflect that.    So it goes from SG to SH to SI and so on so anything higher alphabetically  meets SG specifications it's just that much better.   Your Breva manual was published years ago oil's have improved and the nomenclature has changed.    So bottom line SN will work great in her  Breva.

So it goes from SG to SH to SI and so on so anything higher alphabetically  meets SG specifications it's just that much better.

The additives got changed, and so this may not be true between all types. That is, the SG oils evidently have more of some additives than the newer formulations. The following is from http://news.transdiesel.com/blog/passenger-car-motor-oil,

"So while API SJ, API SL, API SM and API SN PCMOs are perfect for modern petrol engines, they may not be ideal for older engines, especially those fitted with flat tappet cam followers.

Because of the high sliding load of flat tappet cam followers on the camshaft in older engines, a higher level of anti-wear agent is desirable to prevent cam lobe wear.  The perfect anti-wear agent for this job is our old friend ZDDP.  And ZDDP at the concentration of previous API SH engine oils."


I'm either going to get SG rated oil or a bottle of the additives previously mentioned.

Yes, that's correct.
