oil leak on new car

Pretty sure the manual on my Ram says 10k but the dealer will change for free every 5k so who am I to argue.
I had a oil leak once early on but luckily it was just the filter worked its way a little loose.

It goes against what we have all been programmed to believe and follow since we've been driving, 3k was the standard for many years, it was Jiffy Lube that made it a marketing tool.
Most manufactures have had 7500 mile service intervals for several years (Toyota being one of them) I've never followed that, always did 5k, never had an issue until the '07 Camry we had, 3500 miles you better add a quart, or it might not make 5k. Only Toyota I've ever had that used oil, regardless of miles, was a known issue, and only the worst ones were repaired with new engines ( 2AZ engine is not rebuild able )


There were many that went 15k+ on ORIGINAL oil fill from new, The oil life monitor cost GM A LOT OF $$$$ because of its inaccuracy, a lot of timing chains and tensioners, and a lot of engines on warranty, on top of all the other under designed crap they pushed out.

X2. Quick change places want you to come in every 3000 to get that money. My 1967 Ford Fairlane owner manual recommends every 6000 with normal driving. That was way back in 67 when they didn't strain the dinosaur bones out of oil like they do today.
 
I let Blackstone Lab dictate my oil changes. I still use dino's in my pre-2000 stuff, and every submission I have says I still have life left between 8-12k intervals (Rotella). My 2000 and newer vehicles I use full synthetic...on mobil1 Blackstone said I had life left after 12-15k oci's. And most recently I've been running Amsoil in my Lincoln and Edge, and they had life left at 16 and 18k. So that works for me. Sure a quicker oci is cheap peace of mind, but I've never not had a gas engine last between 225k and 250k...and thats with 5 total oil changes or changed every 3k. I'm far from an oil expert, but if Blackstone results say I'm ok...I'll take it.
 
I just change everything every 5k miles. I use castrol and 1/2 quart of lucas oil stabilizer. Tundra has 145xxx miles and I drive it hard (hard not to with 381hp at my right toe). My trail truck has 235xxx miles and it gets driven kinda hard a couple times a year and sits the rest of the time. DD has 120xxx and fights I85 every day.
 
I change the oil in all my cars every 5000 miles because it's easier for me to remember (change at 50,0000, again at 55,000, again at 60,000 etc. ) and that's the only reason that I do it that often.

This s good point and I generally agree... however my Mazd5 is supposed to go 7500 between changes... but the oil is clearly nasty by 5000. After the first couple at 7500 I switched to 5000 anyway, the way I see I plan to have the car a lot longer than the powertrain warranty, and it the damage done by the infrequent changes won't show up until much later.

How in the world can you stare at the oil and call it nasty? Unless you are doing lab test on a sample the oil isnt necessarily "dirty".

There are many driving conditions that dictate oil change intervals. I use black stone labs and my 08 f250 oil change interval is 10k right now. I hope to hit 12k when I send the next sample. My wife's car hyudai 2.0t they told me try 9k because she drives almost all highway. My 11 mustang gt 5.0 they said try 7500 on first sample while ford does say 10k im going to send samples to see even though it has an 8qt pan.
 
What physical location are you taking the oil to have it sampled?
 
Since we're talking oil. My new dually doesn't get driven much. Only pull a trailer with it. Ive owned it for almost 2 years and only put 6400 miles on it.

I drive it to work one day (30 mile each way) every couple weeks so it doesn't sit for long periods of time.

I changed the oil after a year of ownership but am wondering what y'all think. Should I change more often then a year? Do oils break down while sitting?
