Anyone use this with E85?

Lucas upper cylinder lubricant, NOT Lucas Safeguard

"Apparently" it aids in lubricating injectors and fuel pumps, I've seen simular stuff advertised specifically for E85,  VP racing M2, which (again) "apparently" is the same stuff as this or the safeguard (safeguard isn't compatible with diesel though). 

Anyone use this with 98?

Anyone use this with diesel?

I used it years ago in a old Torana I had, as no leaded fuel was available, seemed to work just fine, I think it was 2ml per 1ltr of fuel.

It also "apparently" boosts octane, by how much?????? 0.0001 RON, but, it at least doesn't knock it down, "apparently".

Why am I asking, a mate was having issues with his fuel pump, "apparently" the E85 he was using ate it, from there we started talking about fuel injectors and the requirement or advantage to lubricant the plunger, yada yada yada, just add beer.....

This post has been brought to you today by curiosity and the word "apparently".

It was used ages ago by many [me included for a while] to compensate for cushioning effect of lead in super.  Was supposed to make your valves and valve seats last longer....because everyone kept telling the world that all our valves and seats would erode away with this unleaded poison we were forced to use.

It may well do this, but with modern valve seats and valves it was proven over time to be totally unnecessary.  And older vehicles with cast valve seats [or cast iron heads with seats cut directly into the head] and 'softer' valves got updated and then went on to do another million miles.

I can remember these sort of additives on every service station counter available in little 40ml plastic shots - one per tank fill.

These days you rarely see it anywhere, and with good reason, it was totally unnecessary.  We lament the loss of super, but the sky didn't fall?

In the case of E85...I don't know, but suspect the same.

There's a very big difference between "lubricant" in upper cylinder lubricant and "lubricant" in terms of what might keep pumps and injectors happy. The former is lead or calcium or some other mineral based thing to cushion the valves on the seats, and the latter is going to need to be some type of oily lube.

      It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.

      By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.

      There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
