Valvoline NextGen possible low oil pressure

So have you perfected cold fusion as well?

Dude, water is a fluid and is NOT compressible. The reason moisture in a hydraulic brake system is a bad thing is that water will boil under the temps encountered in a braking system, and water causes rust and corrosion.

Technically, water IS compressible, but granted not at the pressures seen in a normal braking system. I agre with your other point: moisture does cause a number of problems in braking systems.

Our walmart still have bunch of next gen on clearance, and they stock back white/red bottle on the shelf, all green bottle is on clearance section.

to the OP what oil filter did you use ? any oil leak ? I know rear main seal or oil cooler gasket is leak on these engine, i have both leak, but not bad, still getting 45 psi at cold, and 40 at idle hot, and 42-43 crusing.

I suppose I should have said that water in not any more compressible than any other liquid...

The answer is yes, You can compress water, or almost any material. However, it requires a great deal of pressure to accomplish a little compression. For that reason, liquids and solids are sometimes referred to as being incompressible.

I simply disagreed with you, may want want to temper the hostility a bit. Agree that water causes other issues over time and note that technically water by itself does not cause rust, rust only occurs in the presence of oxygen

Anyway moving right along.......

I stand corrected, you can compress a liquid. You learn something new every day. However, I don't think you'll get any measurable liquid compression in the oiling system. My original point is: a 50% decrease in oil pressure is not directly the result of the oil. Its mechanical.

I drive a bus based on a Chevy Express 3500 DRW Chasis with the 6.0L
and I believe the oil pressure sits about 20psi at idle, and around 40psi when driving. I'll check tomorrow, and update if it's different. It runs mystery bulk conventional from work, and a Wix filter.
(The conventional is mystery as I don't do the maintanence because its a company vehicle)

My response was a little snooty, and for that I apologise, but you stated that "water is easily compressible", and that's not a matter of simple disagreement, it's a matter of being incorrect.

NP, I was incorrect as well. I should have stated that water vapor is easily compressible. The issue with moisture in a breaking system is when it heats up and causes a spongy pedal (and long term corrosion/rust issues you pointed out)

Apologies to the OP for hijacking his thread, am curious if he swapped out that filter yet

 

[ottotheclown]

I always go by: if it worked well before you did this or that go back and find out if it was what you just did. SIMPLE

My personal favorite response on a question about oil pressure from a 2001 GMC Sierra owner "its got double digit oil pressure...keep running it. "

Sorry for the absence guys. The problem was a bad stepper motor for the oil pressure gauge, which after some searching, I found out is a common issue for my body style truck...actually for many GM vehicles like the Silverado, Tahoe, etc. My dad who has a 04 had several broken motors. The motor was $3 on eBay, and the same motors run all the gauges(alternator, speedo, temp.) It took me about an hour to fix, and my dad was quoted $600 for the dealer to fix his speedo. Here is a video on how to fix the speedo, but the same fix works for all gauges with these stepper motors. http://www.youtube.com/watch?v=gWELz904fj0&feature=fvwrel
Buy the X27.168 motors as these are the better ones. No problems with the oil, still looks clean and was about $5 after a $20 rebate at Advance with a PureOne filter. I plan to keep using it if they keep offering specials. Thanks for all the help.

When my oil stash finally runs out (still over 100 quarts) I would buy NextGen unless the other Valvoline is cheaper. NextGen should be every bit as good as the regular Valvoline.
