Mobil 1 Extended Performance OCI

[artbuc]

I use 5-20W Mobil 1 Extended Performance on my wife's 2010 Acura MDX. She burns a little oil (fortunately not as much as most of the 10 X's do). She is driving around 6k miles per year. Is it ok to change oil only every two years at 12k miles? Mobil says this oil is good for 15k miles but they do not specify a maximum time interval.

Also, do you see any problem going to 5-30W to reduce oil consumption? I add a quart every 2-3k miles.

Thanks.

I just posted an used oil analysis in the used oil analysis section, though on a 2.0 Dodge Caliber. 12k might be pushing it, but you are adding fresh oil over that course, I didn't have to add any, but it'll easily do 8k miles according to Blackstone.

12k mi (especially with the generous makeup oil) and 5w30 (to attempt at reducing the oil consumption) are A-OK.

6k miles per year sounds like a lot of short trips and if that is the case I wouldn't go 2 years.

I use Mobil 1 Extended Performance in both my cars. My '02 For Exployer and my wifes '11 Chevy Equinox. My car has a very minor leak which isn't worth fixing to me, and I've gone 1 1/2 years on a change as the miles are low. It has 205 k miles on it now. My wife's car has been a big disappointment. It uses a 1/2 qt of oil in 1500 miles. So in 6k miles, I've had to replace 2 qts of oil, but at 5k the oil life monitor says to change the oil. For what Mobil 1 Extended Performance costs, it's like throwing away good oil if you go by the monitor. Her car has less then 54,000 miles on it and was dealer maintained up to the point I bought it. So I've let it go to around 10 before I change the oil. Blackstone's stand on when to change oil is, they go by miles NOT TIME.

I believe Mobil actually says a year on EP.

I regularly go over that and it is always fine.

That would be my concern. My wife uses her Avalon in a similar fashion (it's an 07 with only 70k miles). I've used EP 5w30 for the last several years, the car exhibits zero consumption, and I change it annually. No problems. I'll almost certainly be doing a used oil analysis on it this April when it's time to change, so we'll get some idea as to whether this plan is working. Two years with all that short tripping, even with generous top offs, would scare me a bit.

I have been doing 10K OCIs for 41 years with Mobil 1 oils in all types of engines with outstanding results.

Considering you add 3 quarts of makeup oil per year anyways, I would not perform any "oil changes", until you do a filter change. Use a Fram Ultra, and fill it, run 3 years and add 9-10 quarts of makeup oil along the way, then change it and add fresh oil.

If you use a lesser filter, I'd not even do the oil change at all then- change the filter once a year, and with makeup oil and the pint in the filter, you've already replaced 80%+ of the oil in the sump... which is not far off from how much you will end up getting out anyways. Testing and math shows nearly every engine leaves 10-15% in the engine during an oil change anyways, which shows you're essentially turning over the entire sump yearly anyways. The only thing you really have to consider is filter loading.

I know some people may take offense to these comments, but it's a true statement. When you've got an engine that consumes/leaks oil at a rate faster than the oil is overwhelmed by mileage or contaminants, you're just throwing money at it. On a 9-year old vehicle that you seem to be intent on keeping until it's not worth much on the open market, this kind of plan will minimize your operating costs while still providing plenty safe protection for the engine. JMHO.

Vanilla Mobil 1 5w30 every 2 years with a used oil analysis for assurance.

 

[DavidJones]

Seems to me the most important consideration is how those 6,000 miles are put on.
Never or seldom up to operating temp?
30 miles ever time she puts a key it?

Why two years? Why not 1-1/2 years? Do one in early spring after winter and the next the following year in mid-fall.
Example: April 1st 2019 and Nov 1st 2020..... every 9K.

I'd choose M1, 10w30 high mileage and change it every 5000 miles. There are a number of Honda owners who have mitigated the oil use issue by going to higher viscosity synthetic oils. The High Mileage oil is a great product for your exact situation.

The M1 high mileage oils have superb HTHS numbers (viscosity when hot) and excellent low temperature pour points (generally around -40F) . This is indicative of a very high quality base stock. The additive package is also sufficiently robust to keep additional wear at bay (in other words, it's not the watered down additive package so common in today's regular oils) . It's good to remember that low tension piston rings often fail to seal properly due to very mild wear and that additional viscosity can help. There are plenty of examples where oil consumption is reduced to acceptable levels by such a switch.

My Ford V10 engine went from consuming 1qt every 5k to essentially nothing when I made the switch from 20 to 30 grade. Your Honda won't care either. Go for it.

 

[The Critic]

No, I would replace it annually unless the vehicle is used exclusively for long trips (hundreds of miles at a time). Typically, a low annual mileage stems from short trip driving, which results in condensation (moisture) building up in the crankcase. I just replaced the oil and filter on a family member's 2013 ES350 which had gone 19 months and 10K (exactly 10K) on Toyota 0W-20. The oil had evidence of moisture contamination and the oil filter housing was starting to get stained. I would HIGHLY recommend annual oil changes if not more frequently if this car sees any short trip driving at all.

Our 2008 CR-V runs to about 9,800 miles to 15% on the maintenance minder. I have followed the MM since we bought the vehicle new in January 2008 and it currently has 155k miles, mostly with Mobil 1 Extended Performance 5w20. Next oil change will be in about 3 months and I plan to stick with Mobil 1 Extended Performance but I'm going to try 5w30 this time.

My wife has an 08 CRV...that engine just seems so easy on oil. Never consumes a drop of oil. I've gone 8,000 miles between changes, 5,000, used conventional, synthetic, blends, different weights, different brands. It just doesn't care. Come to think of it, I don't think I've done one single repair (outside of maintenance). Nothing. 127,000 miles and not one issue.

Overall ours has been reliable but we have had 2 issues within the last year. Issue #1 was a bad AC compressor that I had to replace. Honda actually extended the warranty on these but ours had already expired by the time it went out. Local Honda service manager told me they replaced so many compressors in our area that he actually kept them in stock until 2014 or so.

Issue #2 was the passenger side wheel bearing started making noise back in December and I had to replace it.

It has been a great vehicle and I almost want to keep it just to see how many miles it can rack up. Vehicle has no rust and the paint still looks pretty darn good to have been parked outside. Just for something different and the amount of miles, I'm going to a 5w30 next oil change. It does consume about a 1/2 quart every 10k miles or so.

None of the Ford engines I have owned that called for a 20 wt. oil uses any oil in 10K OCIs.
