What Motor Oil Do You Use for your TL?
#243
When I deleted my EGR, my oil life went from 100% to 0% in less than 1200 miles....The driving style or location or any of the did not change....before the EGR delete the oil used to last 6000 miles according to the MID....
None the less, I have always kept the OCI's to 5000miles....
and yes, I do not follow the manual word for word....

I know everyone knows it already but the MID obviously has no way to sense oil condition, it's a calculation with cold starts and trip length along with total engine revolutions (not mileage) having the most weight.
The EGR possibly helps warm the coolant up a little quicker. It reduces combustion temps under part throttle. I can't see any way it could actually reduce oil life but maybe the ECU defaults to a different algorithm when the CEL is on.

That's interesting. I'll have to see where my oil life is right now and see if it goes down quicker than normal with the EGR deleted.

I introduced redline motor oil when the motor was at 147K and I remember you saying the first time you introduced redline, you burnt through some oil since it has a lot of detergents....so the next oil change I did in 3K miles @ 150K and the oil was perfect...
@156K the oil life went down to 5%. I changed my oil with Redline at 157,500 and also did the EGR delete...
@ 158,700-ish (after 1200-1300 miles) I was at 0% oil....I wrote to Inaccurate and he said he had seen this as well...but he did mention, it only happened for the first 2-3 times....I havent seen the oil % go that low sooo quick....now I get down to 0% ~ 4500miles....I am at 169,2xx miles...
I am hoping going forward, the MID % wont fall as fast....

MID oil calculators, and not just Honda, simply plug a bunch of variables into an algorithm to determine oil life.
Variables being ambient temperatures, engine coolant temperatures, oil temperatures, number of cold starts, engine load, fuel use, etc.
And really, they are pretty good at it. Changing on the MIDs schedule won't hurt you one bit. BUT I agree with Anil, as enthusiasts, change it every 5k.

There is a lot of speculation as to exactly what the MID uses for it's calculations. I have yet to find any documentation that spells this out in detail. The SM and OM are fairly vague: "Based on engine operation conditions and accumulated engine revolutions..."

so you're agreeing that it's probably a good guide for the average joe on when to do it. As long as it's not an arbitrary number, it's good to use. Or, if enthusiast, as mentioned, stick the 5K thing.

It makes sense that total engine revolutions, not mileage is used. It makes sense that starting temperature and duration of each drive would have a huge effect. That was my guess and I ended up buying a white paper on the MIDs which basically said the same thing.
Anyone wanting more info, not just speculation, take a look at some SAE papers. It will cost money but it gets past all of the BS and speculation.

Matt, honestly, if you read it and researched it, that's good enough for me. Somewhat ignorant for me not reading it directly but I have a lot of confidence in your knowledge.

I'll dig around for that paper when I get home. I can't copy it but I can paraphrase some of it's contents.

MID is fine IMO for anyone not tracking. Remember, some folks actually get 5K intervals from the MID on a regular basis. These are folks who probably do a lot of stop and go driving and/or spend a lot of time in VTEC. Changing oil before the MID interval is up certainly doesn't hurt anything, but it's a waste of time and money IMO.

I was asking if frequent short trips would matter to the MID because for the last 9 months (M-F), I've taken 10-16 short trips everyday and am now at 30% with 6k miles. Other than that I've had occasional drives on Friday and Sat evening but not as many short trips.
Going off of the MID alone one would be led to believe they have another 3-4 months left and might as well change at 1 year.
Something's not adding up.
For the record, I've never gone off the MID and don't even look at it much. I typically change it between 6-7k miles but this was the first time I've had that many miles stretch out over 9 months. Typically I'd hit that in 6 months.

So yesterday on my lunch break I went to autozone. saw that they had a sell on royal purple oil. the tag said 5 qts for $30.95 and that saves you $18. so i said what the hell I get it while its on sell. So then I go to check out and get ready to pay and the cashier says "total is $2.14" WHAT??!! i asked her if she rang up all 5 qts and she said yes. i guess they are no longer going to sell 5W-20 royal purple oil so that had it marked down to $4 a qt and you get $18 off because of the special! one hell of a deal so I went back and bought all that was on the shelf lol. if you dont believe me just check out the receipt! definitely made my day!

ya idk if its only at that store or what? I tried looking online and they dont sell 5W-20 royal purple on the autozone website just 5w-30 and 10w-30 so if they have some 5w-20 on the shelf u should be able to get this deal

haha....that should be on the left hand side
but yeah, RP is a thin oil, not sure if I would want to put the 5w20 in my TL or the wifeys Lex...and makes me wonder why are they not going to sell it anymore and why is AAP in such a hurry to clear them out....never seen 5qts of a "renowned" synthetic oil going for $2 for 5 fuqqing qts

Great, who wants to start a thread on when to change the oil: hot or cold?
I've done it both ways but usually change it after a drive and 1hr cooldown. This weekend I parked the TL (driving the Accord again) and was about to change it cold on Saturday morning until I asked myself the question.
After a bit of reading differences of opinion around the net, it appeared the consensus was to change it hot or warm (as in my case).

^^^ warm is how I do it...
I usually get home and let the car cool down...cool enough that you can touch the oil pan....not sure if am right though....gotta wait for IHC/94eg!/nfn/ to chime in...

i change it right away.... which is in about 30min getting all the tools from my 2nd floor apartment, jack, jack stand, drain pan, funnel, torque wrench, towel, oil, filter, washer.
and by the time i spin the filter off and oil spils out, it's HOTTTTTTTT .
but not hot enough to burn. i wear those blue gloves. double wrap.

Ill start mine for a couple minutes and let it idle so the oil is barely warm. I don't see the benefit of getting it super hot. I change mine between 3-5k depending on conditions so I'm not worried about every last drop of old oil. If I was doing extended OIL CHANGE INTERVALs I would be a little more concerned.
Right now I'm at 6k and broke (f-ing IRS) so it's doubtful it's getting changed before 7k but thankfully I don't have to worry with the oil I'm using.
You guys should see how much is truly left in the oil galleys, crankshaft, etc. on the GN I have a Preluber and once all of the oil is drained out I hit the Preluber and at least another quart comes out as it pumps the internals including the oil cooler and filter dry. This is why I change the filter last. As soon as I trigger it oil starts flowing out of the pan again. I also use it to pressure everything back up before starting. But my point was I don't concentrate on getting every last drop out of the TL because there's still plenty oil left in the internals.
Ill probably do a mini flush this next time. Drain the oil, put 3 quarts of Redline in; run the engine for a minute and drain. Repeat if necessary. I bought enough oil last time to do both cars twice but after doing the fiancées Murano the oil was still dark so I drained it out, put 3 quarts in, ran it and then filled it up. 8 quarts wasted, 13 used for one oil change. That sucks.

13qts per oil change....what a newb
I never thought about it that way....I usually measure what comes out, but I am an expert at spilling so I never get accurate measurements....and 2 oil changes back to back and an OCI of 7K is essentially the same as oil change every 3.5K in my book

I am a very rare one here. I use Schaeffers Supreme 9000 5w-30 with Wix or Pure One. Thinking about the mix IHC uses to use on the TL for a few changes and go back to Schaeffers, but i have alot of Schaeffers left. I have 3 - 2000-2001 F-350's Turbo diesels, 1 - 93 F150, 2 - Fox Body Mustangs and 04 TL. So it makes since for me to buy in bulk from Schaeffers with free shipping.
