Oil Change - Hours vs. Miles

Now the the 'o5 and up come with a Hobbs meter is it better to change oil by the mileage or by hours ?

I average about 73 - 75 hours per 3000 mile oil change (very low idling time).

Just wondering what the concensus was.

Thanks,

DED

Re: Oil Change - Hours vs. Miles

Well, my plan was do it by mileage, but then I noticed the hour meter and wondered which is better myself - good timing on this thread.

BTW, I planned to change the oil filter at 200 miles, but I blew through that like it wasn't even there. 325 miles +/- tomorrow. Close enough.

Re: Oil Change - Hours vs. Miles

Nope,
There is a huge variance as to how the different trucks are driven. 3000 miles is the same for everyone. (With the exception of towing and slight speed variation) 75 hours for you and 75 hours for me could be drastically different. In automobiles the best way to measure intervals is mileage.

In heavy duty boats & construction exipment the best choice is by hours since mileage is a little harder to track on a bulldozer!

Your best choice would be to get an oil analysis done for your specific driving habits and see what oil change interval works the best for your driving style.

I change mine every 5,000 and rarely ever tow anything of substantial weight. I don't perform oil analysis or anything like that.

I don't agree. You could let your engine ilde for a lot more hours than I do. I've read here where some guys let their trucks idle for days while they're off snowmobiling. We all know extended idling is not too good for the oil, valves, egr, etc.

Re: Oil Change - Hours vs. Miles

I asked this question a long time ago and the consensus was between 150 and 200 hrs.. Your driving habits would put you at about 6000 miles @ 150 hrs or 7500miles @ 200hrs which coincides with the factory recomendations... IMHO , 3000 mile oil changes is a bit premature but it's a free country. [img]/ubbthreads/images/graemlins/smokin.gif[/img]

Re: Oil Change - Hours vs. Miles

You should consider both. Most people only consider mileage because that is the only thing they can conveniently track. Since you can track both you should consider both. 30 miles is considered a reasonable mileage for an hour idling. So if I wanted to use a 3,000 mile change interval, I would simply change it every 3,000 miles unless I went over 100 hours.

At 3K miles on the oil the last Blackstone came back with a viscosity of 62.8 (norm is 69-82).

What kind of oil are you using? This guy is doing oil changes at about the same intervals as you{He had a few over 6k miles too).. His viscosity didn't dropped that much [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Re: Oil Change - Hours vs. Miles

3000 miles for me.
I tow heavy and about 90% of the time.
Oil analysis shows my viscosity is always broken down at 3000 miles.
No longer a 15W40 oil.
I will stick to miles.

Re: Oil Change - Hours vs. Miles

Hours are far more accurate. I could let my truck idle for a month straight and according to mileage I wouldn't need to change my oil. Mileage is great for changing axle/trans fluids etc.

Actually, oil analysis is the most accurate and when it says I am not at 15W40 anymore at 3000 miles.... I will go by that.

My ScanGauge shows 0.6 GPH at idle (625 RPM) and 1.0 GPH at high idle (1200 RPM), in case that helps your calculations any.

Re: Oil Change - Hours vs. Miles

I agree with the posters that the Blackstone analysis is the best indicator of oil and engine condition, but it is fairly expensive and will vary depending on usage.

Let me propose an alternative solution to the mileage/hour-meter debate. I go by fuel consuption. On summer fuel I plan to change my oil at around 18 tanks of fuel. On winter blend, 20 tanks. So, if I do a lot of low speed highway mileage, the fuel usage based change puts me at ~5000 miles. If I am doing a lot of high GCVW towing at high speeds, thus working the engine hard, the fuel usage method will tell me to change the oil ~3500 miles or a little less. It works really well for when you do mixed driving. Tracking is fairly easy. Just a notepad and pencil.

This system is not perfect, but it does account for changes in usage and idle time. As my truck ages, I continue to monitor my oil condition with Blackstone about every third or forth oil change. FYI, my Blackstone results have been excellent.

What do you guys think?
