Oh, right. I ended up getting Penrite HI-PER semi synthetic cos they didnt have the other. It says its low ash, meets API TC and JASO FB levels whatever that means, and meets or exceeds ISO EG-2, apyic and JASOFC, its all greek to me. Says its good for mowers, chainsaws, seedoos, go carts and as lead replacement.
Yep, it s quieten down the cold engine clackity-clack, yet to see how performance and economy goes...


if your gonna use it..dont use synthetic...they reckon it doesnt burn up properly...get some of the Castrol Active 2T...its red in colour and its mineral oil.

I agree with Krankin, the mineral Castrol oil would be the way to go, in case the semi-synthetic does leave some deposits. It's something I won't risk a $4,000 DPF on. However, if you get FD-rated synthetic that's different - it's good stuff. You have to sell your kids to afford it, the stuff is like gold.

You could use that semi-synth oil in your lawnmower. It's overkill - most 2-stroke oils for lawn mowers aren't exactly the cream of the lubrication crop and they still hack your lawn just fine.

JASO is the Japanese Automotive Standards Organisation. FC is the rating of the oil. FB is sort-of low ash but not quite good enough for our diesels. FC is fine, more refined (equals more expensive) and FD is the top-notch stuff that is usually put in the crankcase on DPF-equipped vehicles. It's also usually fully synthetic and manufactured specifically to be good at lubrication, ultra-low at leaving deposits and very tolerant of heat. It needs to be - the blow-by pushes this stuff out of your crankcase and into the intake manifold and it's combusted.
 
^^ Oh, ok. I wont use it anymore then. Needed some for my whipper snipper anyway!! What i can report after a bit more driving tho is this; performance seemed better than usual. Ran my finger over tail pipe; dry as a bone.
Q; do d22 zd30's have dpf's? Mines a 2004 with a full exhaust but standard dump pipe.
Also, the mazda rotary community are very big on Stihl two-stroke oil. Any of you guys looked into that?
 
The only Navara (that I know of) with a DPF is an auto D40 STX. Every other model does NOT get it.

There MIGHT be a Thai (ST) D40 auto with it.

No D22s had them, as far as I am aware.

As for Stihl 2-stroke oil - again, if it's not very low ash formulation, it's worthless in our cars. In a chainsaw/snipper/lawn mower you just remove the spark arrestor, clean it with a wire brush and put it back on and the crap is gone. You can't do that with the DPF or the CAT in our cars.
 
Anyone with a dpf running 2-stroke? Im just wondering whether the burn-offs are more or less frequent with the 2-stroke oil. (i dont have dpf- its a d22, zd30)
After reading the link in the first post on this thread i decided to use the penrite HI-PER that ive got since it seems to tick all boxes, and am noticeing that where-as with straight diesel the exhaust fumes have that strong acrid diesel smell that stings your eyes and nose, with the 2-stroke it is virtually odourless!
Makes me think maybe diesel with 2-stroke really does burn alot cleaner...
Also; Egt's seem.pretty much the same,
idle is much smoother( it has shut up a rattle i had behind the dash at idle, and the side mirrors arnt doing flash-dance anymore)
Seems smoother all round,
power seems better.
 
I didnt read this whole thread but i will a bit later tonight when i get a chance but two things i can say fromy experiences with 2stroke in petrol is it will block a cat conveter quicker and sthill chainsaw oil is the ducks nuts. coming from experiences in rotarys a lot of people premix fuel due to rotary usually burns engine oil to lubricate apex seal. a lot myself included disconect the pump that does this job then premix to send clean 2stroke oil in instead of dirty engine oil and peopke have been doing it for 20+years in rotors. most people in the rotary world have concluded that sthill 2 stroke oil does an exceptional job it burns cleanly and dpesnt leave a residue like some others and people have seen very little wear in motors that jave been pulled diwn that were running sthill. big chainsaws operate at high rpm allday in logging industrys and most if them still run sthill oil. just my two cents and cant wait to read this thread later

Yes, I have used it and yes, my car has a DPF. The DPF light has never ever come on, and I've never ever had any indication that it's been regen burning so it's really difficult to say if the frequency of burns has increased.

What might be overlooked in some of the discussions about 2-stroke oil is precisely WHICH oil to use. From a brief read, it would appear that Stihl 2-stroke is JASO-FB, which is a "low ash" formulation but that's still too coarse for our vehicles, particularly those of us with DPFs.

The absolute minimum is JASO-FC which is "very low ash" and best still is JASO-FD "ultra low ash". Problem is, the FC oils cost about $42 for 4 litres and the FD oils cost $69 for 4 litres.
 
yeah didnt really make for good reading got to page 16 and got sick f the pissing contest going on instead of conversation about the topic.
but meh, probably does have small benefits the only possible downside i could see is the possibility of carbon build up but i doubt that would be an issue due to the small amount of oil used and the ignition temps created in a diesel.
that said im to lazy to do it, itl get enough kms before it ***** the bed for me.

Has anyone been able to confirm that it causes more carbon build up? If you read the link to the other forum in first post they talk about how there is less carbon build up with 2-stroke.
 
Im not saying it will. i know it does help to cause carbon build up in rotarys from my past experiences but even that is debatable due to the fact the afr is usually set rich which also contributes to carbon build up. I dont think it would be much of an issue with a diesel imo
 
well there is a few pics around of glowplugs and injectors pulled for an engine that was running 2T and they are very clean compared to no 2T.
it won't cause carbon build up in a diesel because its burnt as its injected. in most petrols and rotarys you could get carbon because it coats the walls/head before its ignited.
 
Is there fact to support this
Thats why im asking.

Very interesting!

who's pics????
 
So i tried adding 300mm of CASTROL 2T two stroke oil today to a tank of fuel just to see if it made any differance.

Well i have to say im happy with the results.

For a long time i have been able to hear a "ticking" noise under light acceleration and while maintaining a speed, it just seems to load to be normal, and whats puzzling is that it goes when you put the foot down hard.

Well after about 10-15km of adding it to my tank i can honestly say it did make that "ticking" noise allot quieter.

This does make me think that the noise is NOT a timing chain tensioner and is definitely an injector noise.

Anyway so i will leave it out of the next tank or two and see if the "ticking" noise comes back, if it does i will add it to the diesel on a more regular basis.
