4stroke oil

[Quasievil]

Mobil 1 pretty clearly has a vulnerable VII package

Without getting into technical crap

Mobil 1 didnt become the worlds number one Synthetic oil by having a "vulnerable VII package"

Porsche, Mercedes,Aston Marton, to name a few, didnt choose Mobil 1 for its ""vulnerable VII package"

But I hear what youre saying I often hear stories as to how the engines have issues because of oil, only yesterday a guy running Valvoline in his race car was dissing the oil "Bloody Valvoline has cost me $70k in engine rebuilds this year"

I nod and go oh yeah really .....oh no..........thats bad.............,what a freckin tool, had nothing to do with anything else, just the oil.

I liked that page & saved it. Read it all and thought a pretty good time saving summary of info out there - keeping in mind the need to keep an open mind. (Had to edit my post re tin being an extreme presure additive - it's zinc, not tin. Sorry-Doh). Recognised a lot of cut and paste of articles I've come across before. That guys test of viscosity stability shows Mobil 1 up top of what was sampled so surely can't be toooo bad!

Intend to dig further into synthetic/semi synthetic area. Seems a pity Castrol won that court case & synthetic distinction a bit blurry now.

A lot of guys do use oil for diesels in their bikes. Always seemed dodgy to me as high detergent/buffer content (for dirty diesel engines) not needed for bike, but maybe some value in these high quality oils if you pick the right one. I see one of the Rotella flavours only fail JASO motorcycle spec because of very slightly higher ash content, which can apparently cause piston, plug deposits. Maybe no big deal.

Interesting comment on ash, elf does ok in that regard, what is the spec that is most relevent for shear does anyone know ?.

	Sulfated ash content (ASTM D 874)	Viscosity index (ASTM D 2270)	Kinematic viscosity at 100°C (ASTM D 445)
Mobil 1 Racing 4T 10W-40	1.0	164	13.8
Mobil 1 Racing 4T 15W-50	1.3	166	19.4
Mobil 1 Racing 4T 20W-50	1.0	150	17.8
Mobil Delvac 1 5W-40	1.35	151	14.8
Elf MOTO 4 XT TECH	0.83	163	16.89
Elf MOTO 4 HP ECO 10W40	0.82	153	13.7

Foo, getting techo now - I wish I knew what ash is doing in oil, lol. Looking at that chart, is it a viscosity stability improver?

Looks like it's the left over from added metals like magnesium/zinc.

The odd thing is I read it was good for determining detergent additive content, dunno how that works out.

Ok read a bit more, turns out magnesium is a detergent, for some reason I'd not have guessed that.

Dude dont put Delvac 1 in a bike ffs, its not recommended at all.

I ended up putting in the Motul synthetic listed in the manual.
main reason for this was, every thread i read about the subject turned into "my god of oil is better than..." and "i've ran XXoil for XXXXX hours and my engine still goes 'hard' "
I have a suspicion that Motul's high $/l is partly because its good stuff but also because of the confusopoly that the main brands enjoy where no customers really know whats going on and pick the one that good marketing, and fear of the unkown, leads them to.

I use Mobil 1 racing 4t in my KTM and had done so for a year and its worry free, the engine looks and runs mint.

I've been using castrol 4T on my RFS engine for a year and it still runs mint as well, but... im not sure thats the best test.
From what i've gathered lately some of castrols oils haven't rated well when tested after they have been run in engines and im now looking for something else.

I can handel the cost of motul every 5000km on my lc4 but the cost of replacing it in my trail bike after every few rides is enough to investigate justification.

Quasi - When it comes to high quality diesel oil, why is it not recommended at all?

Cant be arsed going back to find right quote but that 20l drum you $$ on tm for $176 is a good deal thats bout as best a trade price as i can get normal rrp is 225 could be from one of the bike shops that have close down of late tryin to get some $$ back as i know they wont take it back

Thats a good question and the answer I guess is simply (from a Mobil perspective) Delvac 1, XHP,MX etc is designed for Diesel engines exclusively.
They hold endorsements from Engine builders like Detroit,Mack,Cat etc etc but you wont find an MA or FD endorsement from JASO etc, so would this be a warranty issue if you blew your new bike up, yeah I would think so.

Quality Diesel Oils these days are all built with emissions in mind and there are a bunch of different systems used for compliance purposes by the makers, EGR, ACERT,SCR,DPF/DOC blah blah they all use different process and need the involvment of the oil to aid meeting the standards set out by the various governments of the world.
Another factor ie Euro Trucks need different ASH levels than USA Engines this is also reflected in the oil,So what is the ash level requirement if any on a bike?

and the factors do go on and on...................................so which Diesel oil are you willing to bet your bike engine on???

For me (yes Im indoctrinated in the MOBIL way) I wont fuck with it, if MOBIL say MOBIL 1 Racing 4t for my bike then thats what it is, why would ya consider putting aside the recommendations for the opinion of a web forum

Remember these Oils arent just made up in the bucket out the back, most reputable oil makers throw millions at Oil research so I will go with their recommendations every time.

At the moment I'm thinking of going fully synthetic, but it's a compelling price that semi-synth.

I think it's a agricultural dealer in Chch, but could be wrong.

One other thing, how relevent is noise, elf xt fully synth makes my head rattle like crazy ( was the same on the KLX450 ), but go Castrol GPS semi synth & it's back to being more quiet again.

Well as I actually work for Mobil I can assure you thats bollocks and smells of agendas as opposed to facts.

Have to say i did a crank on mobil 1 ! But then it could have something to do with third gear exiting the cases on my sportster at 8000 k !
Bastards wouldn't give me a new bike and a year later it did the crank, but it must have been the mobil 1 aye

I been running castrol GPS in the bikes and do notice the gearbox becomes clunky after a say 6 hours of track ! Got recomended to try the castrol power 1 racing at twice the price, but i will still change it after a race weekend ! haha it just keeps getting more expensive !

Need to convert my wood burner into an oil fire, hehe now that would be a go seeing i have a doz 4l containers of 4/6hr old 10w40 in the shed !

yeh i get a bit top end noise but then yamis seam get a small bit anyway (nothing like ive heard on some of the rmz though) the oil has never made any diff.

heres another topic then-

if bike oil is so awesome, why not then used (4-6 hour old) bike oil in your car / van / truck whatever ?

what you tryin to say put 6-8 hr old used bike oil in car???

[B0000M]

yea pretty much.

4-6 hours in a car is about 400km

or is bike oil actually fucked in 4-6 hours?

Ok but sorry that has to be the dumbest question on here have you filtered the shit out that come of the clutch etc etc for your bike oil would you put that in to your car i sure as hell wouldnt. Cost of a car engine rebuild for save a few bucks ie: bike holds what a litre. No way id do it.
