I only change when the light tells me to..

I have gone over 9K miles btw an oil change..

Always synthetic..


no oil loss at all..

 

1 litre / 5000kms. i usually change the oil at the 1 down level. has done this since new

 

thanks for all thge responses guys and gals

 

I follow the light as well, and have never made it over 5K w/ synthetic.

I actually have dino in it now - we will see how long it lasts.

W/ Syn oil , I use between 1/2 & 3/4 qt every 3K.

The car has a 2800 stall - that may make a slight difference.

The oil light can't tell what oil is in the car. It uses a series of calculations that are based on temp, rpm, load, etc to judge the oils lifespan. It is a "dumb" system that can't actually measure the oil for wear. But if you are running synthetic (and it is set for regular oil) you should be quite safe to follow it. I ignore mine and change oil every 5K with Mobile 1.

 

I run Mobil 0w40 syn. the last oil change at 3k included close to 20 passes plus regular driving, less than 1/4 qt.

 

I probably use one to two quarts between changes.

 

I ran synth this past oil change and had to add 1/2 qt at 3k. With dino oil, it never used any.

 

At 3,000 miles I have zero oil to add. Always used synthetics, currently using Mobile 1 0w40. If I wait until 4-5000 miles I may add a 1/4 of a quart, but it is rare.

 

I just changed mine today. I got just over 5 quarts out of it (of the 6 that I fill it with) at 4,500 miles. So, this time it only used 1 quart. At one point, I put in 6, found it a little low, added one, went autocrossing and got 4 out a little later when it was changed (total use 3 quarts). It seems to vary on my car.

 

Thanks for all the input. I have been looking to purchase an LS1 and just wanted to see what the acceptable limits are.

 

125000 miles on my motor.. Uses none

 

Excessive.

 

1 qt every 2k miles or so.

 

I threw another quart in last week, and I just hit the 5K mark with Mobil 1.
