Looks good but I wanted to do the change this weekend. Just bought the truck and don't know when it was last done.

 

Well now you are just being silly

 

I'm getting ready to change the oil right now with 4 gal of Mobil 1 5w40 standing by. I see many others using this viscosity but the manual says 5w40 is only good to 30degF. I know there are syn 15w40s out there. Is a 5w going to be OK for a NV summer?

At 100 degrees the 5W-40 acts like a 40 weight.
If you are worried about a 5W-40 synthetic you should also worry about a 15W-40 dino oil.

 

Hey Silly,

Good to hear from you. Good luck with the oil change this weekend.

I am going to repost one of our customer's comments on here recently...for your reference.

Feel free to call or email us anytime if we can be of service!

I have always used 5-40 Rotella, changed at 6 to 7 k miles. 2 original injectors left, 2 replaced at 80k for cold start -buzz flash loaded at that time, and 4 at 96 k when the fuel pump went out- inductive flash loaded at that time.

No head studs, Original turbo, stock air filter, 4" turbo back exhaust. I am current on flashes. Egr cooler, EGR valve, intercooler replaced at 88k. Alternator and batteries replaced at 110k. Other than that she is stock and original.

The truck lives in Los Alamos, this is in the Jemez mountains at 7500' It does get cold up here, we have a average of 6 feet of snow, morning lows November AVG 26F, December AVG 19F, Jan AVG 18F. Feb 22F.

In September I had the oil changed, By October I noticed that my remote starter was not catching on the first try every morning, and she was producing gray smoke, the smoke was 80% 18 inches from the exhaust using the ringelmann chart for up to 10 minutes.

If I did not let her warm up the turbo did not spin up until the engine exceeded 2000 RPM.

In early November I added the HSS.
Over the next few months I noticed improvement in start time, smoke output, and the turbo returned to normal operation.

By Feb the smoke was less than 10% on initial start and less than 5% after 30 seconds again using the ringelmann chart.

During this time there was no changes to the engine, no parts replaced except an inner tie rod end.


So, as it got colder, the engine started faster, with less smoke, and the turbo resumed working properly. This is not a “think” “sorta” “kinda” opinion.
This is a proven fact; HSS fixed my cold start issues this winter. I used a ringelmann chart on the smoke; I had a timer on the crank time. There were no other variables changed. I even used the same diesel brand all winter; they switch to #2W on November 1st so that was consistent.

So, in conclusion, it is the opinion of a P.E. , Masters in aerospace eng, and a Dr of chemical engineering, that HSS caused a measurable and significant change in my trucks cold start performance.
I assume that some will attribute the change to the tie rod end though."

Mobil 1 in, probably no sweat. As for additives, show me the science. If the guy is a PhD in Chem, lemme hear more than smoke trail and turbo onset.

 

Have been running Rotell 15w40 since my o5 was new and no problems,the 6.0 likes it and I do use Lucas oil addative faithfully. I have worked on big diesels and most owner operators will demand the Shell rotella and add Lucas,they get well over 400,000 miles out of them so must be good

 

Ditto... and have been using in my truck since 50,000 miles and I now have 148,000 miles with zero (repeat zero) problems!!!!

All oil analysis reports come back 100% perfect!!!

Of course, I use only Motorcraft oil filters from Walmart which are only $17.99 - $19.99/ea... or I use Racor made (OEM manufacture) oil filters from my local Int'l truck dealer!!!

And... change your oil every 5,000 miles... even if using a synthetic oil (regardless of brand)... they all shear down... so every 5,000 miles is key (whether running synthetic or not or even if running a by-pass oil filter).

There... I just did all the "leg work" for you.

Good luck,

 

I ran regular Rotella for the last 30k miles and just changed over to Rotella synthetic--the Internatonal counter guy said that Rotella was great for the 6.0. I have 83k mile son the truck and change the oil and filter every 5k and haven't had any problems. You'll be fine.

 

And... change your oil every 5,000 miles... even if using a synthetic oil (regardless of brand)... they all shear down... so every 5,000 miles is key (whether running synthetic or not or even if running a by-pass oil filter).

Now where are you getting this information from !?!? I know you haven't run your syn oil to 7,500 miles and had it tested !!!

The syn most likely does shear down as well, (probably not as quickly) but I have to believe the qualities of the oil are all still there at 7,500 otherwise how are they getting this oil to last 10,000 + miles? in other applications (and yes I know our truck's are HPOP powered oil destroying diesel's).

Facts. Show me the facts !!

 

I got my Valvoline Extreme Blue 5-w40 at Oreileys. They had to order it from the warehouse, but it came in a couple of day. Price was good too. If you have a Oreileys see if they can get it.

 

No facts... just common sense.

Fact - The 6.0L shears oil down to that of a 30 weight so it is irrelevant how the oil does in other motors.

Fact - It is easier to remember changing the oil every 5,000 miles than every 7,500... and the 5,000 miles interval matches up with every other service required on the 6.0L motor and tranny.

Fact - Why wait for one's oil to use up it's additive's then change... just change on time and not have to spend the money for oil analysis... this would save money to.

Fact - Ford's states to change the oil every 5,000 miles for severe duty service which is normally about what 80% or more of people drive.

Fact - I used Motorcraft 15W-40 motor for 50,000 with zero problems... I switched to Rotella-synthetic 5W-40 for better cold weather starts and better protection of my turbo bearings and that synthetic oil is purified and cleaner than convential dino oil.

Fact - Posted below is a graph from a by-pass oil filter company that shows that without a by-pass oil filter, it is at the 5,000 mile mark that the cost versus benefit of a by-pass oil filter pays off... at 5,000 and below... not needed or less effective... becuase one's oil is not really that dirty and the full-flow OEM filter is working just fine.

Fact - I have been posting on FTE since January 1, 2004 and 5,000 miles is what 99% of people here post and claim works... so with that... I almost clasify that bit of knowledge as fact due to owner performance and recommendations.

Hey do what you want... but I will always error on the conservative side regardless of what the oil companies claim, what by-pass oil filter companies claim and what a few poster's claim as to how many miles they drive before changing....

Good luck.

 

yup 5,000 is magic number

 

My 04 Pontiac GTP has an oil life indicator based on how hard the car is driven, I still change the oil every 3,000 miles (synthetic blend). Just better to error on the side of caution. I'll do the same on this truck (5k), don't really need a repair bill. :0)

You gotta be kiddin me??? when are you guys gonna stop..............
