should i switch to thicker oil?
should i switch to thicker oil? hey fellas .. today i was drivin down the freeway ( drivin it pretty hard) and noticed when i got off to a light that my oil pressure was around 20 psi which is wierd 
cuz usually idles around 35-40 when itz warm and when itz cold ruffly around 50-60 now when im driving goes back up to around 40-50 .......i use vavoline 10-30 was wondering if any of u guyz had this problem or should i go with a thicker oil i dunno kinda lost for words ne advice would help thx..

Chance of your transducer ( the electrical pressure gauge that moves your panel gauge) is unlikely. A Diagnostic tuner could tell you. Are there any puddles when you stop...Are you burning it? What's the exhaust color?
naw bro ...no puddles.. not burning anything (cept lil more oil than usual just thought it would be the shorties... had em for like 2k miles ) i cant see any colors in the exhaust..

Not sure. I would say a compression test, to check your rings. Get your oil lines blown out. Low pressure air. After that if it's still low...Probably have a clog in your block. The oil goes thru the block to lubricate the pistons...If none of that....Ummm..My boy says drive it down here and he'll run it over for ya. Cuz we're all out of ideas
Three things come together to make your oil pressure lower when you've been running it hard. The oil becomes thnner when it's hot, your clearances become larger because the block is hot, and the idle rpm is lower when the engine is fully warm causing the oil pump to not spin as fast. Mine does the same thing after getting a new shortblock, it will be 40 psi at idle when it's warmed up, but only after driving for half an hour or so it is down to 25 psi. As for the oil pressure twitching, if you watch closely you'll find that it twitches as the idle rpm twitches.
