2 Stroke oil?

[Chas]

I know adding 2 stroke oil to a diesel helps lubricate parts other oil doesn't reach (apologies to Carlsberg) but would it have any benefits in a petrol engine?

 

[Chris]

Probably not unless it's a 2 stroke Chas. Not thinking of adding it to the Jaaaag are we?

Adding 2 stroke to diesel is supposed to lube the IP and help compensate for the low sulphur in Derv, allegedly. In a modern ECU controlled 4 stroke petrol engine I would’nt go anywhere near it. For starters it’ll probably write off the cat(s) not to mention the numerous emission control sensors. It was a sad day when 2 stroke bike racing came to an end. The exhaust note and the smell of the Castrol R made the hairs on the back of your neck stand up. Poxy emission regs.

I was Chris but wanted to know if it was safe, I've got a 20ltr container in the garage.

I’m with Towpack on this. It will destroy your cats. At the very least. Don’t give it any ideas of breaking down ok! It’s parentage is, somewhat associated with a certain brand that likes to break down. I’ll say no more!!

Just behind the drivers seat there is a wind deflector which on mine has disappeared probably got sucked out by the wind, I found a replacement on eBay for £99, but before buying I checked with a Jag dealer, £198+VAT , and I thought Toyota spares were expensive.

The days of mechanical engine wear are over so no point in adding anything to extend life. Just another snake oil myth in my book.

I just put a new (higher compression) 7.5:1 piston in my 1958 500cc Ariel 'VH' bike. The +20 bore was de-glazed with a hone at the time.

I'm adding a very small amount of 2-stroke oil to the fuel to act as an upper cylinder lubricant until the new rings have bedded in.

Injection pump is lubricated by the fuel, so modern low sulphur fuel has less lubricating properties for older injection pump design, just my opinion of course.

I imagine leaded petrol would murder your car so i'd say absolutely don't do it !

That Ariel is a thing of beauty Bob, I like that a lot

I think this is quite common among owners of old bikes. I was talking to a couple at the NW200 last week and they both did the same with their Nortons. Special “upper cylinder” potions are available but a smidge of 2 stroke amounts to exactly the same thing IMO and works out far cheaper

Iv'e been adding a couple of glugs every time i refuel my old Smiley face Transit for years, runs better, quieter & better consumption, is a diesel though.

Have you ever tried it Frank? I was of the same opinion before I tried it, I was amazed the first time I did, it really makes the engine sound and feel smoother.

Lovely old bike, there's something about a big single.

This is in the cruiser I take it? Out of curiosity, how much do you put in?

 

[Chas]

Yes that was in the Cruiser, 500ml per tankful.

 

[frank rabbets]

No I've never tried it Chas. Not mentioned in the owners hand book and as I don't have a relevant qualification I just put fuel in the fuel tank.

Just a note to use mineral 2 stroke oil not synthetic

Just a note to use mineral 2 stroke oil not synthetic

Why's that? I heard that synt is better at staying suspended, mixing easier. So I use about 100 ml synt 2-stroke per tank.
Unless I use 2nd-gen biodiesel (synthesized) which lubes better, which you actually can hear.
