Engine oil compatibility with alky injection

[Alky V6]

With these cars.. and the subject OIL.. hehehe.. how bout adding ZDDP, EOS, Synthetic, etc..

I don't understand what you're trying to get at with this statement. Am I missing something here? Is this another hint that someone suspects I have a hidden agenda by asking a question? Look, if you think I'm trying to pull something here, why don't you just let the cat out of the bag and let us all know what you think, including me. I'm starting to get the feeling that there's a lot of people that think I have a 'hidden agenda' when I post. What is it? Don't be shy. I can take it.

Or is it easier to make assumptions about a person behind their back?

I would suggest that alky injection manufacturers should be taking the bull by the horn on this one and start doing some careful studies on this subject.

The only agenda here is to inform people. Would you rather I kept my mouth shut and let people drive around with potentially harmed oil in their oil pans? I have a unique experience with my engine setup that has forced me to do a lot of research and learning, mostly from hard knocks. I'm just trying to pass info on so that maybe someone will save having to rebuild their engine. I guess I could say that's an agenda, but I don't see how it could be a harmful agenda to anyone.

Are you maybe referring to how when commercials talk about cigarettes causing cancer, how it might affect cigarette sales? Maybe in your mind, people shouldn't be warned of the potential harm from smoking cigarettes?

I'm not saying here that small alky injection kits ruin your oil. I'm asking the question, does small alky injection kits affect oils with differing oil additive packages? If it does, and you use a small alky injection kit, wouldn't you want to know what oils to stay away from to avoid potential engine damage? I can't imagine why anyone would not. Can you?

It sounds to me like you may be perceiving that I have a 'certain' agenda. Being the curious cat that I am, and one that likes things to be out in the open here, what do you think that agenda might be? Let's discuss it.

Maybe this topic just makes you uncomfortable to have to think about what may or may not be happening with your oil? I can understand that. Most would rather stick their heads in the sand, than try to find out the answer. I'm getting the sense that maybe there's a lot of those here. With a few exceptions, of course.

WHOA DON -- Chill man, I was not attacking you, or I wouldn't have apologized in advance on my origional post.

Now comparing cigarette's to Alky Inj is a bit of a stretch

Seems like poor Don is not going to get an answer that will make him happy.

Maybe he should try some CHEMICAL ENGINEERING FORUM:frown:

Maybe he guesses he'll have to call his oil rep and ask to speak to an oil engineer. He was hoping that maybe someone already had some interesting information they could share on the subject. He means, here's all these kits in use and no one has bothered to do any research on the possible affects alcohol might have on common engine oils? Wow.

If he finds anything out, I'm sure he'll share it.

You can put your head back in the sand now.

Very interesting information.

Handbook of Lubrication and ... - Google Book Search

Anyone that uses a small alky injection kit can relax now. It appears that as long as the engine and oil are hot enough, any alcohol and water (a large byproduct of burning alcohol) that gets past the rings will evaporate before it can attack the additive package.

I realize you didn't mean to attack me. It's cool. What gave you the impression that I had a hidden agenda?

Does this mean you've done some scientific studies?

 

[Alky V6]

What about E85?

I've come across some mentioning that there is special E85 safe engine oil on the market. Has anyone seen this?

 

[Alky V6]

Don,
Your are assumming 20%.. it may be that only 8% or 4% is needed to stop the knock detector from going off.

I wasn't assuming 20%. I was following your lead. You mentioned 20% in one of your previous posts on this thread.

 

[GNVYUS 1]

I run E85 all the time on my 69 GTO and the oil looks great at 1k miles but I've decided that $20 is not a big deal and change it at that mileage anyways. I only put on about 1k a year so what the hell.

I think your trying to turn a molehill into a mountain .. There are a LOT of cars around here running Alky with lots of miles on them .. Have to remember your a race car running straight fuel . No comparison . oh "curiosity" killed the cat

I think the book link covered it, but wanted to post up some math for everyone to chew on

Meth boils at 148 F, your oil is at what temp? 180-220?

Lets say you stage and make a 10 sec run, 15 sec on alky. 3600 seconds in an hour, at 20 gph of methanol. .005555 gallons, or .7 oz a sec times 15 seconds is 10.5 oz, or .08 gallons of methanol injected. How much blowby do you get? Lets go what I would call high, at 5%, and that's 0.525 oz. Take into account that your oil is well over the boiling point of meth, and will be even long after shutting the engine off, as long as the air has someplace to vent, I don't see the meth being a problem. If you blast down the highway on a cold engine and shut it off, sure, might be a problem if you do it every morning, but I don't see the burnoff rate being overtaken by the introduction rate.

If you are really worried about it, find a way to keep your oil above 150 F, and it should all disappear.

Based off of his posts, I don't think "he" (himself) is concerned, only troubled about the average alky consumer "flooding" the motor @WOT and contributing to eccessive cylinder and ring wear, without intervension. . It's only a matter of time before "someone" finds out first hand!

Excellent info. Pretty much follows my experiences. I also remove the drysump oil tank cap when I get back to the pits after each run and cover the opening with a rag so that bugs and such can't find their way into my oil tank. Lots of steam. The rag is damp by the time I remove it. I run a vacuum pump with a open breather on the opposite valve cover. Sounds like I'm doing it right.

I would think that crankcase ventilation is important, so street cars should make sure they're doing more than just simple breathers. Keep the PCV valve working.

Grumpy. I don't understand your attitude about this subject. It seems to have you all puckered up. If this discussion affends you, just sit back and watch or don't force yourself to watch. I would hope you decide to keep participating though. It seems you do have a good amount of experience to share.
