Maybe if I waited too long. Its better to replace the oil before doing so produces a noticeable change.
Unless you have one of these newfangled vehicles thats supposed to break after 200 thousand KM, with replacement cost similar to repair
It’s because the old oil is decomposed and out of grade and it’s additive pack is used up. You waited too long.
No, I dont. If anything I change it to soon.
Then it would have acted the same before and after the oil change. The difference you stated is a difference in oil health. Pennzoil use to go out grade by 1000 miles, longer and you were doing damage and generating carbon deposits in the engine.
I have always noticed when I change oil in anything, maybe you just dont pay any attention or have very low mileage motors. Rotella is a robust oil.
I only noticed when I changed my brake fluid. I can hit the brakes on my vehicle and it would take me forever to stop. swap the fluid and it would stop on a dime.
Now that I have never noticed, but I change brake fluid every two years.
I have never changed my brake fluid before on any vehicle I've owned. But for some reason something told me to do it in this one. Probably really stupid on my part but now I'm sold.
The schedule for changing brake fluid on most new cars is way too infrequent, imo. When it's not clear anymore, and starts turning green/black, it's time to change.
Even at 3k it's noticeable in sedan, jeep, or truck if you pay attention.
On my 66 bug, yes.. but that gets a valve adjustment, points adjustment and timing check at the same time.
Had a 2001 VW that I did oil changes about every 6 months on and never felt a difference. I was driving it a lot, so those were roughly 20,000 mile oil change intervals. Top end looked great at Both 200 and 400k miles (replaced the lifters as preventative), sold it before hitting 600k miles... on the original engine, without anything more than standard maintenance.
I'm guessing that's a synthetic oil. I have on older dodge that doesn't do synthetic, although all vehicles are capable of running synthetic. the lifters clap when I put synthetic in it. if your lifters start banging, go back to SAE 30. they label it as diesel oil now, but nothing changed except they make the synthetic cheaper. some older vehicles just won't do synthetic. I'm a boomer too. woohoo !!
Its a blend
Yes. I am usually greasier.
I had a '93 XJ that completely rusted out around a perfectly running 6.0 with close to 300k. I called it the Flintstone Mobile for obvious reasons.
There shouldn't be much of any change if you are changing it within 5K miles. If you notice a change, it is possible you are experiencing oil dilution from unburned gasoline (dirty or leaking injectors). The only other thought I have at the moment is the filter is getting really dirty (blowby and contaminants, stuck pcv) and enabling the filter bypass circuit, especially in cold weather with the 15W40.
Looking forward to the day of the pillow.
