I'm in the mind frame to start changing my own engine oil on my 06 Tl with 15,000 miles. I know that my Acura Dealer uses Valvoline 5-20w. Just coming off the Mobile 1 website, seems like they have oils that can last up to 5000 and 7500 mile intervals. What do you recommend?

 

I use Mobil 1 5W/20 with the Mobil 1 M1-104 filter.

 

Ditto

 

Same as above.

 

i use Motul 8100 5w-30......

 

Castrol Syntech (full synthetic 5-20) as acura says 5-20 is required.

 

Actually, 5w-20 is recommended, not required. It is sometimes difficult to find 5w-20, although best to go with what the manufacturer says.

Check out the 3G Garage... Tons of info on this topic in there.

 

I thought it was hard, but look for a black 5qt. bottle of castrol syntech...

 

Pennzoil 5w20 synthetic

 

amsoil full syn, 5w-30 with a pureolator pure one oil filter. oil is rated at 25k miles while changing the oil filter half way through.

 

Royal Purple 5w-20. Probably will use Penzoil Plantium next because it so cheap and easy to find compared to RP. RP is excellent but I have to use ebay to find my weight and from prior exp Penzoil syn is pretty damm good.

 

Does anyone change their oil beyond the 3,000 mile interval?

 

Every 5,000 for me (M1 5-20)

 

Amsoil 5w20.

 

Honda Filter and Mobile 5-W20. I change my oil every 5K and tranny fluid every other oil change.

 

While you can use the Mobil 1 M-104 filter, the better one to use is the M-110. There have been numerous discussions of oil & filter on the board.

 

I use Mobil 1 and change at 3,500 to 4000 miles. I know this probably more frequent than required but some habits die hard. I use Mobil 1 is all me vehicles after the break in period.

 

Mobil 1 5W-20 with Mobil 1 oil filter M-104. You can also use the M-110 which is larger than the OEM Acura filter on the outside but I doubt there is any difference on the inside. If it has any advantage at all, it might be in greater heat disipation (marginally).

I figure if Acura thought a bigger filter would be better, they would have put it on there. They are the ones guaranteeing the engine. The cost is the same.

 

Tis strange but if I remember right the Mobile -1 reference book lists the m110 for the 2004 TL yet lists the M104 for 2005 etc..

Clearance with the lower control arm has been mentioned as an issue with the M110. I've studied this numerous times on my 04TL. No way are the two going to make contact short of a massive crash that bends the right control arm at the same time the suspension is completely compressed.. Maybe they had a few make contact in 04 and made the change..?

Staying on topic I use 5W-20 Castrol Syntec in the "colder" months here in TX.. I switch to 5W-30 Syntec for the summer - and of course the M110. I do believe I achieve a 1-2 mpg increase in fuel economy with the 5W-20 (above the AC difference).

**4500-5500 mile intervals

Cheers

 

My acura dealership does the oil change for free so i'm stuck with that for a while til i do more research on what oil, oil filter to use

 

I do my own oil changes per the MID (~6500 miles in my case) with Motorcraft 5W20 and an OEM filter.

I even use a torque wrench for the drain plug.

 

Good old Ford

 

Double Ditto

 

I go 6K miles between changes with Mobil One.

 

I have yet more questions. Does the computer actually monitor the degradation of the oil or does it judge the oil degradation on a time basis (time intervals) and reflects that in a percentage format? Also how many miles can be driven until you have to change the oil (Due Soon pops up). Now I ask because If I go fully synthentic, the oil change intervals can be anywhere from 10-15k or even longer.

 

the computer monitors how hard you drive your car. I would never go 10k miles on any oil, but that is just me.

 

So the sensors can not tell the difference between oil blends; ie. fully synthetic and synthetic blend?

 

not as far as I know

 

Correct, the MID uses an algorythm that evaluates RPM, load, cold starts, idle time and other factors to recommend an oil change interval.

I ran the excellent Motorcraft synthetic blend to 5% remaining and performed an oil analysis and found the oil still had a good safety margin of TBN and wear metals were still very low. Plus, for less than $2/quart, it's hard to beat.

 

Fords use that oil and look how they run at 100k miles. lol, j/k. Good price.

 

I will be coming up on my oil service soon. I also use the MID to tell me when to change the oil. I will either use 5w-20 Pennzoil or castrol synthetic.

My 97 Pontiac had almost 200k miles using the MID and synthetic oil.

Its a waste of oil otherwise.

I would not drive any car where I had to change the tranny fluid every 10k miles.

Again, big waste of money.

100k miles interval on synthetic fluid in the Pontiac GP GTP without any tranny failure. 50k miles currently on this interval. 47k. before I switched to synthetic.

I do work for a oil company, so thanks for keeping me with a paycheck
