What? it's easy to feel if the oil is getting old in this car, the roughness from revving the engine alone says a lot. At below like 4.5k the difference isn't huge but @ high rpm is very pronounce. It's like it's not happy for me to stay pass 5.5k.

But I think it might has something to do with my engine getting old too.
Usually the first 1.5k after oil change is buttery smooth then it slowly degrades.


Ok, I know that may sounds like out of this world......but It's very obvious if I don't change oil within a month or two after tracking the car.

Roger, you can feel the difference in the smoothness of the revs and how freely it wants to rev. Especially how it pulls above 4k, as mentioned.

The engine just sounds and feels more effortless with fresh oil.

Have you ever wondered about when medications are prescribed to adults, that they seldom take into account the patients body weight. In toxicology labs, dose levels are determined by milligrams or micrograms per kilogram of body weight of the test animal.

Windshield label from the shop, but now I'm learning those aren't as big a deal.

Heh, ya, I know such things about medications.

It's just about being in sync with your vehicle and feeling literally every piece of information that it's presenting to you.


Kindof like knowing how to satisfy and please a woman in the bedroom, there's subtle non-verbal queues you pick up on and experience.


It sounds like you just aren't as in touch with your vehicle as some of us are.

I figured it was only a matter of time before you worked sex into this somehow.

So, if my so called sex life, is getting rough, it's time to change the oil ..??

(well, I have had that same jar of Vaseline for quite a while, maybe it's gone bad ..)

Right? I'm not sure how I would describe it except that the engine just feels a little rougher.

Before my oil cooler, I started to feel the change around 4500 miles. Now it's around 6000. With a pressure gauge I can also see a slight drop at the same temps. Am I changing sooner than necessary? I don't care. I feel better about it. That's all that matters.

I actually don't know what changes the feel of oil so I know I'm not gonna be able to convince you that I can feel the oil getting old. Usually 1 oil change for me is about 2 trips to cali to track or mountain passes + some driving in town.

I think this is really a prospective issue.



To me the possible reasons for oil feeling old are


1. Dirt, I live in Vegas, there is a huge amount of dirt. I can pop any interior panel open and there is gonna be a layer of dirt/very fine dust. Ya, Nevada & South Cali........ tumbleweed & dust devil. I'm sure my engine sucks in a ton.

2. Heat Cycling the oil? Usually for me to go to track means 8 hours round trip to Cali track plus another 8 hours on track, so 16 hours of straight driving. I usually do this or just simply enjoy my time doing canyon runs within the first 2000 miles after I change my oil.

I'm kind hard on my car while I'm on certain roads, I don't really shift till redline & does tons of engine braking for the entire length I'm on that section of the road.
I drove the entire section of Mt. Hamilton HW130 staying near redline. *Humfrz you said you love that road.


PS:* Most of the time I only drive 5 miles over speed limit on public highway & I don't race others..... >___> If i encounter someone on those mt pass i slow down and build space till i can have a go again.

PSPS: I'm not counting metal shavings in oil cuz i have magnetic oil filter and drain plug.

It's not dirt. You're feeling the drop in viscosity/lubricity as the oil cooks and shears. Some of it is also the filter getting dirty. I've tried just changing the filter. Feels better for a while but not long enough to make it worth doing regularly.
