Oil Capacity in 95 LT1?

Recently did a oil change (well changed the oil pan gasket) and Chilltons says 4.5 quarts to replace. Not sure this is correct. Other years say 6 quarts. Can someone confirm how much oil I should put in?

Oil

My '96 takes right at 5 with new filter. I guess they're the same. My Haynes manual says 5.

BTW, Walmart changes Mobil 1 for $29. My former Express was $59. With crap filter. Use Mobil 1 filter if you want the best.
 
95LT1 Oil

Vern Corvette from Largo, FL puts in 5 1/2 Qts of oil with filter, Mobile 1
 
I don't remember the 'actual' spec on this but I put in "around" 5 quarts in my 92.

After removing the oil filter, I fill the new oil filter with fresh oil - that's about half a quart - then install it.
Then I drain the pan and put 4 quarts back in it.

I start it and check for oil pressure and any leaks. Then I let it sit for several minutes so all the oil can drain back into the pan. Then I check the dip stick and top off the pan.

So, I'm putting in a 5 quarts or maybe a little more.

Bottom line for me - I don't guess at it, I use the dip stick.
 
I tried the dip stick but the oil is so clean its a little hard to read.
 
I don't know what to say about that. Reading the dip stick does not seem to be an issue for me. Sorry.
 
According to Gordon Kilbrew, the LT1 engine was designed for 4.5 qts of oil when a new filter was installed. The early 92 owners manuals were incorrect. They listed 5 qt.
 
jedi,

If you are having trouble seeing the oil level on your dipstick because it is fresh, try this: Drive your car several days so that the oil starts to “darken” from heat/use.

After several days of use, try checking your dipstick then, maybe the oil will be more opaque for you to check the level. If you have at least 4.5 to 5 quarts in, you should be fine. Just don’t get on it till you know for a fact that you are at the proper operating level.

For comparison, when I change my oil, I add 1/2 quart to the filter before installing and then 4.5 quarts to the engine for a total of 5 quarts. My LT4 measures just right at 5 quarts.

Just check your dipstick when the oil is a little easier for you to see, you’ll be fine.

Exactly right B-17. Great advice. It's real hard to see right off. The Haynes says nothing about filling the filter, but it makes sense. 5 quarts is just right for me too.
And Wal-Mart sells the 5 gallon jug for $22 that you can put the old oil back in.

I think it's fun to do myself, and save $30.
 
tlong,

I had read a while back that filling the filter helps the oil circulate faster after a change and also helps prevent a moment of starvation until the oil pressure is up. How accurate this is, I have no proof, but it gives me piece of mind.

I have been trying to buy the Mobil 1 in the 5 quart at Wal-Mart and I have yet to get lucky!

After the um-teenth time making and effort to buy the 5 qt., I asked a stock clerk where’s it all going. He told me that the Mobil 1 in the 5 qt. is so popular that they can’t keep it in stock. He said he will let a manager know, hopefully in the future they will have a higher quantity on the shelf.

I strongly disagree with running the car a few days to darken the oil so you can easily read the oil level. I mean... you're reading the level so you don't end up driving the car with too little oil in it after the oil change, right? Am I missing something here?!


I find the oil level to be very hard to see with new oil, too. There's a couple of tricks you can use to read it.

The one I use is to turn the dip stick and look at the unmarked back of it (the markings make the oil harder to see). Hold it so the sunlight will make it sparkle in your eyes. You'll see the difference between the glint of sunlight on the wet oil and the dry metal.

An alternative method would be to lay a paper towel over the end of the dip stick. Translucent or not, oil is wet. It will be obvious on the paper towel. Lift it up carefully so you can see where the wet was on the stick, and there you go.


Beware that there is sometimes a little oil just on one edge of the stick. Don't be fooled by this. Read only from where the oil crosses the entire width of the dipstick.

Hope this helps...

Hi Skant,

You’re not missing anything, I think I may have caused confusion, here was my suggestion:

I was suggesting that jedi have a minimum of 4.5 and a max of 5 quarts in and drive his car for several days to darken the oil to where he could see it. With 4.5 to 5 quarts in, he should be well within the “operating” cross-hatch range on an LT1 dipstick. Unless he has a catastrophic oil leak where he is loosing a 1/2 quart a day, this should be enough for him to run over several days to check his oil and add as needed.

Running a car low on oil is the equivalent of saying “hey, would you mind running your body a 1/2 pint low of blood.” It’s just not a good idea. That’s why I suggested running it only several days and not getting on it till he knew for a fact that he was at the proper operating level

I too have difficulty seeing the oil level and will check the back of the dipstick as well, that was a good suggestion to introduce.

B17Crew: Sorry if I sounded irate at all. It wasn't my intention to ruffle any feathers.

I do see your point, but I guess to me... well... screwing up the oil is one of the few ways of totally destroying your engine within minutes. Granted, you'd have to be more than a quart off for that. You _should_ be able to get it close just by how many bottles you put in. But I personally would just be too paranoid about driving the car without having an oil reading at all.

Of course, I should talk... one time I started the car after changing the oil... watched the oil pressure gauge... noticed that it didn't come up after a few seconds... and then had the startling realization that the new bottles of oil were still sitting on the ground unopened. I can't believe how stupid that was. I ran the engine without oil for about 5 seconds. I was having one of those days. I should have just gone back to bed or something.

Maybe that's why I'm so paranoid now. That key isn't turning until I have a reading on the oil level.

Heh. Anyway... hope my suggestions on how to read the oil level help!

Hi Skant,

No need to apologize, you didn’t sound irate at all and no feathers were ruffled! You made perfect sense, it IS risky to drive without an oil level reading.

I have an oil change story too where I made a boo boo: I had purchased the boxed six-pack of Mobil 1 and did the normal oil and filter change.

While I let the car sit to let the oil drain to the pan, I began to clean up. Well... as I’m cleaning up, I notice that all six of my Mobil 1 bottles are EMPTY!!!!!

I put six quarts in by accident. AHHHHH!!!!!!!

Nothing like having to start over.
