Topic: Dumb Oil Question

[blackdiamond]

I know that running too little oil is very bad for a motor, and also that too much isn't good either.  How much is too much?  I have never seen it quatified.  my oil pan is dented (slightly smaller volume) so I usually over fill a bit, but how much it too much?

[RUGER]

the crankshaft will dip into the overfilled crankcase causing the oil to foam.

how much with a dented oil pan is hard to say but i wouldn't recomend going over a half quart

[79coyotefrg]

1/2 quart over full mark is as far as i would go

Besides foaming, too much oil robs HP as the reciprocating mass muss whip through it (crankshaft). It'll create excessive oil consumption by blowing oil out your breather/PCV. Can cause fouled plugs, and at the worst oil leaks.

well  the "worst"  would be sitting on a steep incline and washing the rings with oil then the  engine dies  then when you try to restart iit HYDRA LOCKS

[jr9162]

Yeah that's a definite possibility too.

Why not just change the oil pan.

[blackdiamond [OP]]

The dent in the pan isn't extreme and it has been that way since I purchased the truck.

My question was directly related to adding a stop leak oil product and I didn't want to add too much.  I just changed the oil am now thinking that I like the idea of high mileage engine oil so I added a Valvoline product that is for stopping leaks and adds seal conditioner.  My oil is still suffering from the recent sea foam treatment (very dark) so I will get it changed again soon.  I am thinking about switching from 5W-30 (or 10W-30) GTX to Valvoline High Mileage 10W-40 or 20W-40 to try and stop the small leaks that I have.

I am trying to avoid the Castrol product because I don't like the fact that Castrol Syntec isn't what it is advertised to be.

I run my truck using the Valvoline High Mileage. I don't think it really did much for the leaks but it made a big difference in reducing engine noise. My motor has 250,000 miles on it. When I was using the regular all weather oil it rattled at idle and sounded like it would come apart at 3000 rpm. With the high mileage oil it quieted down at idle and sounds like it will come apart at 4000 rpm. I run 20-50 if I run anything lower it doesn't show any oil pressure at idle. As it is the pressure is just of the bottom at idle and below the centerline at speed. My truck doesn't drip but it seaps oil from everywhere.

rocktoy,   you need a overhaul BAD,  where are you ??  maybe i can help you out


blackdiamond,   after using seafoam you are supposed to change the oil

You know, back in high school a friend of mine used to drive a 2nd gen 2WD extra cab pickup.

He called me and said that his engine is blown. Its smoking terribly. So bad that he can't even see behind him, nothing but blue clouds. He just changed his oil and now its wasted.

I was thinking he melted a piston or something..

Well it turns out that when he went to change his oil, he must have gotten distracted because he change the filter, and then added some oil. Period. Yup, he forgot to drain out his old oil! I don't remember if he added 2 or 3 quarts, because, you know, sometimes you just add a couple quarts and then you'll stop and check the stick. So he checked it and it had oil and he didnt even think twice about it.

So now it was 2 or 3 quarts over full I guess it was smoking from so much oil being thrown in the air from the crankshaft and the old rings couldn't keep it down.

A peek under the hood showed no signs of the engine being over filled. The lines atop the valve cover were all clean. I dont think oil would get into the intake through the breather lines because the only oil present up there is from what is being pumped up, and that really shouldn't change if the level is so high.

So I would say that 1/2 quart over filled is perfectly fine

1/2 quart over full mark is as far as i would go

I agree . At the toyota stealership I worked at 1/2 a quart overfull was cool but anymore than
that and you should drain some back out. Just my

I did have the oil changed after the seafoam treatment, but there is still some residual color left in the new oil.  The oil was perfectly clear before and isn't horrible now, I'm just not used to seeing any color at all.

I added some highmileage engine treatment and plan to change the oil within the month (several hundred miles) so all is well with me, thanks for the information.

[79coyotefrg]

ive always believed if the oil was black, change it       no matter if it had 3000 ,miles or 300

Yea I know I'm looking into a 3RZ or 22re swap.

If you really think about it if your pan is dented you should put a little less oil not more.

[blackdiamond [OP]]

I had that thought at one point as well.  It would explain why the engine takes almost exactly 4 quarts rather than 4.2.
