what no response from people changing at 3k miles? all of a sudden people are changing oil at 7k now?
Most other vehicles I average around 5K, depending on when I feel like it. My trucks get maintenance days every so often, since I treat it like the toy it is I think going through it every so often is good practice. I usually do the oil too if I'm going through it anyway. What I don't do is change the diff fluid every time I submerge the diff, which the manual says I should. I'd be changing diff fluid a couple times a week...
So yeah, I'll fess up - I probably change the oil more often than I need to. I never go 7500-10K.
I confess that I change the oil in my Durango at less than 3000 mile intervals. It's used almost solely for heavy towing (7400 lbs) in the warm weather and short trips in the cold weather. I run heavier oil for towing and lighter oil for the Winter so it gets two changes per year. Since we don't come anywhere near 6000 miles a year, that's a pretty short change interval. It's also exactly what the owner's manaul calls for due to "severe service".
My Toyota goes 7000 to 10000 miles between changes. Bike goes about 6000 before shifting gets notchy, my signal to change it.
Im not buying brand new cars. Its just I get bored with them and want something else.
*shrug* my truck gets an oil change every 5000, and thats 11 quarts
I changed the oil in my Forester every 3750mi like clock work, and with 100k on the clock it didn't burn a drop. It was also JUST starting to develop classic Subaru piston slap.
I just changed the oil in the truck at 8500 mi. 5w20 full synthetic Penzoil. The viscosity was just as the day it went in. I buy good oil and don't think twice about leaving it in there for 9000+ miles. The quality of the modifiers and the shear strength of modern synthetic lubricants is amazing. Plus, I don't beat on the truck. I generally drive to maximize fuel economy.
Now... On the bikes... I'm completely the opposite. I'm a maniac about oil changes. I only use Motorex full synthetic. Oil and filter always changed at the same time. The GSX-R only saw about 1000 miles last season and got 4 oil changes. One of those was done after a day of tuning. The bike made 20something pulls on the dyno and I dumped the oil when I got home. The Sv will probably get an oil change once a month. Maybe twice if it's a month with racing and multiple track days. My approach to the bikes is that they're always getting run hard. If the engine is running, I'm probably beating the bag off of it.
Noel isn't oil a perk for you ?
My bike get 2 changes a year
ENd of season new filter and cheap dino oil for winter sleep
After about 100 miles then change to Synthetic MC oil.
3 other facts
80% of engine wear is the start up before oil pressure builds. Thinner oil and as little as a 10 second delay before power is required will go a long way to engine life.
Synthetics are wonderful but they will creep through very small leaks. If your engine is weeping it is easier to switch back to Dino oil and a lot will stop.
I did full motoman break in but from now on I will change oil bikes within 100 miles and cars 500 miles when new. A large amount of sparkling metal came out with this oil change. Gixer has 12K never burned a drop previous Yamaha burned a qt every 700 then got worse ( recommended break in)
i read before once you go synth, you're not suppose to switch back to regular? is this a myth?
Factory reccomended interval on my Honda: 10K. So reckless of them!
