Can any oil for that fact turn watery after some time or after certain driving styles?I'm using castrol 1030 and it seems like after 1000 miles or so and 8400rpm here and there, the oil starts to look watery and even I might see one or two tiny bubbles on the dipstick. I'm pretty sure there is no leak in the headgasket because The coolant remains to the top and the oil doesn't look discolored, just slightly watery. I have 3500 now after the rebuild and i'm going to swtich to mobil1 sythetic 5w 30 now.

 

if your oil is looking watery, i would think you have some serious problems. does the oil smell any different? how does it taste? seriously, though, you could be getting gas into the oil, or coolant, but you definitely need to figure it out soon.

 

It's because u have a lsvtec!! Do a compression test, drain the oil and look for coolant in the oil or u can drain the coolant and look for oil there but a compression check should be first on the list.

 

Gas in the oil, from a leaky injecotor or where would it come from? The oil isn't chocolatey, looks normal, but you can see how a little water would thin it out, or gas for that matter.

leadfoot, yeah I could see someone blaming it on ls/vtec although it has nothing to with it. My block spins 8400 fine, gsr head bolts, fully balanced, gsr rod bearings, resized rods to name a few

 

I was just kidding about the lsvtec being at fault. Anyway if its gas than u should be able to see the rainbow colors on top of the oil from the fuel setting on top of the oil. If not, have u though that maybe u are just imagining it, seriouesly if it's coolant u will be able to see it in the oil same with gas, if its water than the oil would turn into this dirty white substance. Other than that oil dosn't just become deluted, if anything it will burn but thats it.

 

oil and water dont mix so it wont water the oil down. If it feels watery it might have broken down from the heat and lost it's viscosity.

If you have LS vtec, it means you have a ls block, (duh!) They dont have oil coolers on them. They also are not designed to flow as much oil as the vtec blocks. The oil gets hot and looses viscosity, this is more likely to happen when you are beating on it.(duh#2).

So, if your oil is turning black quicker than usual, it is prolly cuz it is getting too hot.

Your solution will most likely come in the form of an oil cooler.
and synthetic oil, too
or

It could be too rich and the gas is thinning the oil.
