What brand of Motor Oil do you use?

[almostJDM]

Valvoline Synthetic 10w-30 used it in my f22b which was in my old 4door and change it every 3k miles ill most likly change it every 2k-2.5k in my F20B

[d112crzy]

why? It's pointless and a waste of money to change it that often.

[almostJDM]

yea but i wanna keep her clean of any dirt as long as possible

mobil 1 synthetic 5w30, purolator pureONE filter. and i change it anywhere between 3000 - 6000 miles you can tell when oil needs to be changed by the color.

I taste my royal purple if it doesnt taste like grape its time to change the oil.

I love grape.

Maybe I'll switch to Royal Purple once I swap out the F22a... when ever that might be.

i use either mobil 1 full synthetic or valvoline maxlife full synthetic when i do my oil changes o and its all 10w30

[koffin]

Valvoline 10w-30 for me. I change it every 3-4k. I don't know about letting it go much past there. I can definitely see a difference when I change the oil.

Old Oil=Black and Nasty

New Oil=Brownish and smooth.

Later.

This is not valid indication of oil life and performance.
Have you ever seen diesel oil after 30 seconds of it in a running engine?

You are wasting ALOT of money and resources with that frequent of OCI.

Sorry, but no you can't tell by the color.
This goes for almostJDM as well. If you aren't sure if you oil is holding up at 2.5-3k miles, have an oil analysis done. This is the ONLY way to know for sure if your oil is exhausted.
Color means very little.

well i guess it may not be a good way of determining contaminants and viscosity, but if my oil is still honey golden and smells fresh, id be less inclined to rush and change it than if it were black, sludgy and burnt smelling. have you ever brought a sample in for an analysis when deciding if its time to change your oil or not?

Are you looking at the oil on the dipstick? Your oil is sludgey on it?
I have never smelled burnt oil either. Perhaps excessive fuel, but not burnt.
Smell would hold more weight over sight, but not much.

I haven't done an OCI on either of my current vehicles(CB9 and '04 Tundra Double cab) yet. Why don't I practice what I preach? Because I haven't seen a need to yet. I have no problems running extended OCIs. I run the Tundra 1year or 15k miles on an OCI. On the CB9, I plan on running 15k OCIs. That puts me at 2 changes a year. I keep very meticulous data of my vehicles. My logs can help me determine when something might be going bad.

Oil analysis data can tell you if you air filter is bad, you are running lean/rich among other information.

My CB9 operating manual even says to change oil at 7500 miles and they are assuming dino oil with that statement.

If you change earlier, you are wasting money and resources.

The forums there are amazing and insightful. If you still don't believe me on the sight and smell, check that site.

Pennzoil Platinum 10w30 SM I got on sale at Home Depot, plus a quart of Shell Rotella T syn 5w40. Change it when the maintenance "light" turns red. I'll switch to a 5w30 when the PP runs out.

[blizzard335]
