Seafoam IS awesome (oil pressure proof)

[SpikeyGG]

Everyone on this forum raves about how well seafoam works so I wanted to give it a try albeit the unorthodox application method.

I recently added a set of peak-warn gauges so I've been monitoring everything religiously. In fact, the oil pressure gauges' default warn setting was set to 17.5psi which was too high: any time I'd come to a stoplight or let the car idle in the heat it would scream at me. I lowered the warn down to somewhere between 16.5-16.0psi so that it wasn't ALWAYS going off when I was idling. It still would happen when exiting the freeway after shifting into neutral; the oil pressure would dip low and recover back to around 17psi.

I was sort of okay with this since I didn't know what the pressure should be like most everyone else on this board who posts about their oil pressure. I was (and still am) planning on getting one of those Canton spin-on oil filters that you change when the pressure begins to drop, before the seafoam I was hoping that the addition of the oil filter would raise up my oil pressure. Anyway, now I don't have to rely on it to boost up the pressure...

I took the car out for a spin on the freeway to make sure it got up to operating temp. As always while exiting the freeway, I pushed the clutch in and shifted to neutral and watched as the oil pressure dipped into the warn region and stayed there. Bummer, I thought, it must be pretty warm.

I got back to the house and did the Seafoam in the vacuum hose, let it sit for 5 minutes and started it up expecting to see some crazy smoke show but it was pretty lame just a few puffs and it was done. Since it was so hot out and I don't have A/C I was sweating pretty badly so I parked it and relaxed. After rush hour, about 6:30pm I decided to take it out again and see if anything was noticeably different.

Holy crap! When I exited the freeway this time my oil pressure was hovering around 22.5psi! It occasionally dipped to 20psi but never below that. On top of that, according to AccuWeather's hour-by-hour history of my location, at 1:15pm during my first drive the temp outside was 87-91'F and the temp during my second drive was 92-95'F so the oil was hotter which means thinner and more susceptible to low oil pressure.

Anyway, I am now a believer in Seafoam and I wanted to share my experience with you. It gave me an additional ~5psi in oil pressure during idle.

I know, it seems too good to be true but I've had the gauges in for a while (since 4/18) and oil pressure has been a point of worry (warn light showing up). I drove it again tonight and oil pressure is still much higher 20-25psi at idle. The only thing I did was add the seafoam, and I drove it before and after -- same day. Am I off my rocker, or what?

are you sure you were putting in in intake?

I put it in the vacuum hose that I hooked my boost gauge up to (goes to the plenum, after the throttle body). I haven't put it in the tank or the crankcase because reading other posts about it, the general consensus says that it thins out the oil and could cause a spun bearing.

I put it in my crankcase, pennzoil 10w-30 4.5qts / 6oz seafoam; idle for 20 min, changed to mobil 1. Car is working fine so far.

Perhaps your idle RPMs has raised, and is the real reason your oil pressure is now higher.

That's what I was thinking. Perhaps you created a vacuum leak somewhere that you didn't have before and as a result your car idles higher...or perhaps seafoam lived up to its claims and your car runs better (and perhaps idles a bit higher because of this) so you now have more oil pressure. I'm a big fan of seafoam, but I doubt very much that dumping it in your intake is going to do anything for your oil pressure.
