2 Stroke Oil In Fuel

[jims-terrano]

I seem to remember this been discussed before but can’t find it.

What’s opinions on 2 stroke oil and quantity in fuel on terranos. Rustic kept a bottle in the mav so I’m assuming he must of used it. Never tried it personally so no idea about it let alone quantity.

I use the cheapest 2T oil I can get - sometimes

I use 500 ml per tank full every four or so tank fulls. I avoid it prior to MoT obviously. No point in buy synthetic IMHO.

In the summer I sometimes add a full litre - I like the quieter engine and seems more powerful - probably isn't. If you see any smoke you have overdone it!

Do you do this on your Jeep Ted?.

1:200 is the ideal ratio (cost vs benefit), mineral over synthetic. Used it in my '04 3.0 Y61 and still use it in my 4.2 Y60 although I haven't used it in my Mitsi ASX 4wd (2014 1.8).

For ease I just use 500ml/roughly half a bottle per tank (Y61 was a 95l and Y60 is an 80l).

It gives back the lubrication lost when the took the sulphur out of the diesel (that none of the other additives can quite compensate for). Slightly quieter/better running and possibly a slight increase in mpg.

I also like using it in the Trol as it's a weekend toy so doesn't usually run more than once or twice a week and I like to think the added 2 stroke keeps the seals a bit more lubricated (having had to replace main pump seal shortly after I got it I'm not keen to do it again! ).

So far only in the WJ as it has no DPF not tried it yet with the WK.

Sorry, what is a DPF?

I never even thought about putting 2 stroke oil in the WK2.

I got the Costco offer on Diesel Redex last month, so I am running some of that through mine at the moment. The good thing about the big tank on the WK2 is I only fill up about once every 3 weeks, when we go to Costco, as their fuel is so cheap, the bad news is, sometimes the pump cuts out at £99 before it's full... Ouch. :doh

DPF= diesel particulate filter, and they can clog up, most that have the knowledge remove them, Rick

Cheers... Is that the equivalent of the CAT on petrol cars?

 

[solarman216]

No not really, it looks similar inside but has no catalyst, every now and again fuel is injected to burn off the soot, I am lead to believe, but not convinced, Rick

DPF woes

On Mercs when the DPF is in regeneration cycle ( trips in after 15-20 miles plus journey)has to be when the engine is hot the upstream and downstream sensors make the engine run very rich to burn off the particulates in the DPF - it's built into the engine management software. Boy do you know it's working as customers think there is melting rubber somewhere under the vehicle and the back end smells really hot. More noticeable on the larger engines.

If the owner of a MB 250d engine never does over 15 miles in a journey then between services the DPF dash warning light comes on. The dealer will then carry out a computer diagnostic burn cycle to get rid of the build up.. If this fails its a new DPF - they are expensive. On our old Chrysler 300 CRD there were two at a cost of around £1k each. Hence why I got rid when I retired and only did short journeys.

Modern diesels usually have a CAT, it's not just a petrol thing. My 3.0 Trol had a CAT in the downpipe.

I imagine the 3.0 Terrano is the same.

I highly recommend you find out if you have a dpf mate and if you do have one make sure you do a good motorway stretch every so often, the owners manual will have the routine in it, I.e. how fast at what revs for how long etc. They are a costly fix bud!!

Will do... fortunately, motorway miles is not a problem. Actually, reading what Ted wrote about the Mercs, it would explain, a couple of times going down to my mums, we noticed a "hot" smell, but the car was at normal temp, so we decided it was a car we were following.

Yeh, I don't understand it fully but its called a re-gen, it purposely heats it up to burn away the collected crud (diesel particulates) so it doesn't block up. They can be cleaned if they get blocked, there are companies that specialise in doing it, the one I know of uses a kiln in the process :nenau

Having been under the tractor when it was up on a hoist, last service...I noticed a 'mesh like cylinder'...poor description ...sorry....on the downpipe of the exhaust, just under the block.....is this the diesel CAT...?

That sounds like a flexi piece. The engine moves on the mounts and the rest of the system is fixed to the chassis.

DPF & Cats

All the modern diesel Mercs have multiple systems this link is a basic explanation. They have a Catalytic Convertor and a DPF - the petrol models only have a Cat. Precious metals like Platinum and systems designed for the life of the vehicle make them very expensive.

It's literally in the solid downpipe in the 3.0 Trol exhaust dude, from memory there's a slight bulge.

Same on the Terrano 3.0
