Reply to "New 550 owner oil change question"

@DannyP (or should I just call you 'smart @ss?

 The paint fumes must still be lingering from last weekend- I painted a friend's custom buggy frame on Sunday- 3.5 liter Honda V6 power (well over 300hp), Mendeola 4speed transaxle (I still don't get why he didn't spring for the 5 speed, but it may have had something to do with the $2,000 more over the initial 10 or $11,000 required. Very short sighted...), Centerline wheels and over a foot of suspension travel. And I thought another friend's Honda S2000 (220 hp) buggy was fast- this thing's gonna be a monster! Anyway...

All I'm saying is that people think that the 2 quarts (or whatever it amounts to) in the filter, cooler and lines means the engine will never run out of oil, where that oil, not being in the sump is not immediately available to the engine because it's not in the sump. Yeah, the lines, filter and cooler are an integral part of the system, but the sump is where the engine draws from and there has to be enough oil right at the intake at all times to feed the bearings continuously, despite the acceleration/cornering G forces and rpm's the engine sees. I've seen guys wonder why their cars are running out of oil (and the engine has eventually seized)- they thought they had it covered because of the extra quart in the filter and lines but there's no additional volume actually at the pump intake tube. They didn't think they needed the added volume of the sump because, "hey, the engine's got lots of oil in the lines,filter (and maybe cooler)! A member here went through this 3? 4? years ago- he was slolamming his Speedster and thought that because the oil light only came on "occasionally" he didn't need a sump and was surprised when it locked up.

Gene Berg claimed that a 1½ sump was only good to about 6,000 rpm and if the engine regularly lived at higher rpm's a 3½ (for general driving) or 4 quart (for a dedicated drag racer) was essential.

Hey dude- we haven't talked in a while- Al
