Anyone Run Mobile1?

[timswi]

My '11 Sierra 6.2 is coming due for it's first oil change..Was debating running Mobil1 in it...Anyone else do this, and how has it worked out?...I've always used Castrol GTX and have had great performance from that. Debating whether the added expense is actually worth it or not.

I used Mobile 1 in a '98 Astro & had no oil consumption or any engine problem in approx 100K miles. The Shop Foreman had actually advised at the start it was an unnecessary expense. Obviously have no way of knowing if things would have been different using the generic shop oil.

Used Mobile 1 in my '03 Corvette - all 7,000 miles in 8 years, so I know it was really working overtime there.

Unless you're really in for the long haul with your '11, even if you do the changes yourself, it may be hard to justify the added expense.

You can always treat it like "prayer" - won't do any harm to try it.

I do all of the maintenance myself, so labor isn't an issue...I pile up the miles and usually run them pretty hard. The last 3 Chevy's went to 200K with no oil consumption using Castrol...Ran the last GMC to 100K on Castrol too. No problem there either.

Maybe I answered my own question with your help...

I do know that if I'm going to run synthetic, I need to start early...I've seen people start using it at 50K and have valve noise etc...Pretty common thing there. Once they went back to standard oil, all odd noises went away.

I run the Mobil 1 EP (extended protection). It is even more expensive than Mobil 1, but the huge advantage of 15,000 miles between changes ends up being a net savings. Not to mention the labor I save.

I will not ever trust a shop to put synthetic oil in my truck. When I request a product that costs $6-7/quart and they can substitute a standard oil for $1-1.50 per quart, and I will never be able to tell the difference, the temptation is just too high. I know there are honest shops, but the effort to do the change myself is so small that I will not lead them into temptation.

Run Shell Rotella T6.

You can read up on Bobistheoilguy. UOA's show it to be great stuff.

I've been running Mobil 1 fully synthetic in my RAM and Pacifica for 100k + each changing every 8-10k. It still looks pretty brownish at change and still feels slippery in the finger test. I've used Castrol before in many autos with good results but I can never find it in the 5W-20 that my vehicles require.

I've used Mobil 1 since 1967, my first new car('67 Dodge RT, 440 Magnum) and have never experienced an oil related failure, or problem for that matter. I believe it to be worth the expence, which, if you buy it at Wally world is not all that significant, coupled with the extended drain intervals. I change mine out at 10,000 mile intervals, and it is still registering above the "add" level in my '07 Tundra with the 5.7 engine. I tow a fairly heavy trailer during the summer months, somewhere around 12,000#(two antique pulling tractors(3500# and 4500#)+ the trailer. I use 0W-30(even though Toyota recommends 5-20) for cold starts during the winter and the additional heat generated by summer towing(neither the tansmission nor engine heat gauge run differently) towing or not. I recommend anyone who uses a vehicle as I do, use synthetic of some brand

I used Mobil #1 but after using Royal Purple at work in some real abusive situations on some big gear drive and seeing how well it preformed I switched my F350 over to it and it is running cooler, quieter, and 2.5 mpg better mileage.

I second that! :thumbsup:Any true synthetic is better to run in todays engines.

I have not ever run Mobil 1 but about every other Synthetic out there.

My Nissan Titan came from the factory with Valvoline Synthetic and I have continued to use it.

If you like Castrol use there synthetic. They have a great special going on at WalMart right now. I got it for $17.99 per jug. I picked up 10 jugs to stock up for customers boats.

There are no bad oils out there. All meet or exceed the OEM's specs so what ever you chose will be just fine.

I've primarily run Mobil 1 in my trucks, but have strayed to Penzoil Platinum, Royal Purple, Syntec, etc.

I tend to go back to M1 due to price point and past performance. Nothing I've ever owned has had an oil related problem, but that is to be expected these days. However some of my vehicles have been models that notoriously consume oil (the 5.3L in my DD, two 4.2L V6's in F150's, etc) and never had consumption issues with M1.

Thanks guys I will most likely go mobile 1 or some other synthetic...Do you use the AC filters?

I know some people don't like FRAM filters but I have yet to have a problem with one so I continue to use a FRAM Xtended Guard filter which is rated for 10k miles and the extra grip end makes it easy to change by hand without a filter wrench.

I like Wix filters. They're solidly constructed, reasonably priced, and readily availably at O'Reilly, NAPA (NAPA Gold), & Carquest (Carquest Blue). Fram is fine, just a little pricey compared to comparable filters. The aftermarket AC filters are made by Champ Labs and I think most use the ecore design, which seems to have some issues with the felt-like endcaps adhering to the filter media. I don't know if the factory filters are also Champ ecores or not, maybe someone else can speak up on that. I do know that the factory FL820S on my 05 F150 was a completely different filter than the aftermarket Motorcraft FL820S that you pick up at the parts store.

 

[timswi]

I've always run the aftermarket AC's and never had an issue...Did have a problem with Fram on one truck where I would get valve tapping when it was below freezing...A GM tech told me that the Frams didn't have the correct return flow for a 5.7. Changed out the Fram for an AC and problem solved.

Will probably spring for the K&N filter. Given the longer change times on the newer trucks, the price really isn't an issue.

I use Mobile 1 in all my vehicles, including diesel pickup and tractor. Have done so for many, many years. I have never had problems, believe in it. I change my own oil, but intervals are stretched out and I consider it a form of insurance. There are many opinions regarding use of regular oil or synthetic. Seems that the conversation surrounds the value received vs cost. Never seen anything but people saying it is good oil... as are several other oils.

 

[QRTRHRS]

My wife's Caddy CTS calls for Mobile 1 so that is what we use. Perhaps one good reason for that is the tiny cartrige type oil filter.

Since I keep Mobile 1 on hand and want to limit the types of oil I keep, I also use it on all my small engines.

 

[Transit]

With all the competition, all the synthetic oils are good and there may be little difference. On the other hand, oil filters are another matter. If you look into the filter reports where the filters are taken apart and graded at what they will filter out, there is plenty of room for film-flam. Lots of hype on how good we were years ago. Choose wisely.

I ran Mobil 1 for the first 4 years in my '05 5.3L silverado or about 50K. I still changed the oil about every 5,000 due to the 11 zerks in the front end that needed grease. Decided that I wasn't getting enough benefit at 5000 mile changes and am no longer use it.

The truck is Regular Cab Long Bed and only sees maybe 3,000 miles per year at the moment. I may start running Mobile 1 next change due to the amount of time between changes.

Baucom: "I do know that the factory FL820S on my 05 F150 was a completely different filter than the aftermarket Motorcraft FL820S that you pick up at the parts store."

I'd be quite interested in hearing about the difference.
