I've always filled 6.5 quarts and it's right on the full mark. 6 quarts just puts it at halfway in the hash marks.

I use Mobil 1 5W-20 full synthetic.

 

My V10 took 6 qts with the 820s filter. I thought that was alot, My 7.3 takes 14.5 qts and at 23.00 for 4 qts it adds up fast!

 

You are still thinking Chevy.....lol.

 

its shorter and lighter then a 460! THATS amazing!

 

my 5.4 and 6.8 use the same amount 6/6.5 QTs and same filter..makes things easy for me!

 

same COPs also?

 

Are you starting the truck and letting it run for a minute then shutting it off and rechecking oil level?

 

6 quarts brings me to the middle of the cross hairs.

 

Yup. All modular engines of this era, including the 4.6L V8, share the same COPs.

 

Thanks; I've always used Mobil 1 full synthetic in all my cars and will do so on this truck. Sadly, the jug is too small at 5.28 quarts (5 liter). The price per individual quart reflects an amazing markup ($33 for the 5 liter is $6.25 per quart versus $9/quart for an individual bottle), but at least its much better than the cost of having to do something as big as a diesel.

 

This is off topic, but thought I'd throw out the diesel oil change blues:

I do my own oil changes on a 6.0L diesel. Takes 14.5 qt every time. I buy Mobil Delvac 1 5w-40 synthetic, 4 gallons (16 qt) at a time for $105 plus tax. The filter costs $21 mail order. Total oil change (14.5 qt. plus filter) works out to $116.16 plus $10.40 tax. I change every 5,000 miles. Works out to about $0.0295/mile. A lot more than comparable cost for a V10 (maybe 3X?), but we do get some of this back on fuel economy and capability. I average 14.5 - 15 mpg ($0.28/mile at $4/gal). Fuel and oil total about $0.31/mile.

Comparable DIY synthetic oil V10 numbers are probably about $45 for both oil and filter change. For 5,000 mile oil change, works out to about $0.009/mile for oil and filter (about 1/3 diesel expense). Assuming 10 mpg(?) on $3.50/gal gas gives a total bill of $0.36/mile. If only 9 mpg on the average, the total bill would be about $0.40/mile. So, the cost of operating the V10 would range from about 18% - 28% more expensive than a diesel. Neither of these numbers include initial cost and depreciation, which is often bigger than fuel or maintenance costs.

Please don't think I'm starting a diesel vs. V10 debate. I have a diesel as I don't think a V10 could pull my trailer--otherwise I would consider the V10. Diesels have their place and so do the V10 engines. You have to look at the hard numbers and what you need the truck to do when you choose.

 

I actually appreciate the response and admire the analysis from someone who clearly uses DATA rather than opinions as a primary influence to decision.

For me, there were two over-riding factors that made the V10 the right choice: I like working on my own vehicles and know "everything about gas / nothing about diesel" and I drive very little, so I would have a relatively long payback period for spending more for better average fuel economy. I have been getting 10.x miles per gallon in normal driving as measured by simply dividing total fuel purchased by miles driven since last refueling (I drive full to near empty then refuel and reset the trip meter). The truck has only 25,000 miles on it. As of yet, I only pull a 10' utility trailer. My last tank was 10.7 mpg. That included some trailering. The number is likely to go down because I had a remote start installed and the weather has turned cold...spent several minutes getting 0mpg this morning in the driveway. I hope to pull a car trailer or camper, so this was an anticipatory purchase. At the moment, I don't need this much truck, but it sure is fun to have.

 

16 quarts of mobile1 td truck oil every 7500 lol probably what i hate most about driving a diesel .

 

This kind of got buried in all the other discussions and I didn't see it, but to answer your question, yes I am. It took just under 6 quarts and I am about 3/4 of the way up the cross hairs. Maybe an 2 oz left in the last bottle, but I didn't want to risk over filling it.

 

over filling by 2oz wouldnt matter, that dipstick isnt that accurate.
