Why not just use Mobil 1, and just change the oil at every 3-5k miles. Is it sooooo special to pay that much more for a quart of oil to just be able to change oil at 15k miles? Lazyness ? (watch out for sludging for those who change there oil late, VW/Audi had issues)

Sciond

this is just like the intervals I j=have used for years with Amsoil.... I could go 25,000 miles on Amsoil with one filter change at 12,500...... I use the 0W40 in most of my cars

bubblemyster

if you can afford the filter and oil, go for it, im just poor, so im stickin with 5k miles, penzoil 5w30 + filter for 24.99

The point of paying more for Mobil 1 is so you don't have to change your oil every 3-5k. You can change it every 3-5k but then you are waisting the money spent. Its not lazyness, its knowing that you have a quality oil in your car and you don't have to worry about going for an oil change every 3-5k.

0w40 is the european car formula, it is made to meet the spec of Mercdes Benz & Porsche. 0w40 is the Factory filled and Factory reccommended for these car.
Mobil makes the Toyota 5w30 & reccemmends that you use Mobil 1 5w30 for Toyotas. You can use what ever you want Im just stating what Mobil reccommends.

VW had sludging problems but it was not oil related. They were having some internal engine problems. They are aware of the problem and if it happens they will warrenty the engine. My Step-Sister had a VW and had this problem. They warrented the engine with NO questions asked.

Do you know if Mobil recommends STAYING with that formula once you start using it? I normally use Mobil 1 5w30 and change the oil myself. I was considering using the high endurance oil to go through the winter so I don't have to change my oil out in the cold...

You can actually go 7,000 safely on conventional oil. I have went 10,000 on synthetic with a fram tough gard filter in my civic. Oil didn't look that bad either. I think I will stick with 5,000 synthetic. Just cause you can do something doesn't mean its a good idea. At work we have a tester called oil analysis tester you put a clean sample of the type of oil being used and calibrate it. Then you put a sample of the actual used product and it will tell you if you can keep going on it safely or not.

You can switch to synthetic with no problems. Just try to stick with using 5w30.

You can't tell how an oil is just by looking at it. You need to get an REAL Oil Analysis done on it. I can send samples out to Mobil and how it works is they take the oil and break down all the different components and then they tell you what grade of oil it is (5w30, 10w30 .... ) they can also tell you if its Conventional Oil, Semi-Synthetic or Fully Synthetic and they can also tell you what additive packs are in it.
The different additive packs is where you get your specs from. Toyota additive pack is different from the Honda additive pack becasue each maniufacture has different specs for their engines.

You must be carefull going over 3k with your regular crap oil that you get at a quick lube. There is a lot of recycled oil thats is sold on the street that you don't know about. I have been doing this for a long time and found there is alot of garbage on the street. You only know 100% what you are getting if it comes out of bottle. If its pumped out of a bulk tank you have no idea what you are getting.

Your best bet is if you get conventional oil put in your car at a quick lube and its pump in I would not go more then 3-4k on it.

If you wanna learm more about the different specs and licensing in oil go to http://api-ep.api.org/filelibrary/AP...Guide_2004.pdf

The newest spec out right now is SM-GF4 Plus ... you can see more about it on the link above

Good idea, an oil change every 15K miles. But .... i use the Mobil 1 5W30 and change it and the filter every 6K miles. I can get a case of Mobil 1 at BJs/Costco for around $25. I use the Pure One oil fliter ( the blue one, with the red diphram inside ). Thats less then $5 a bottle buying bulk. Now if i change every 6K miles, and make 2 purchases of the oil in bulk over a year .... ( approx. $50 ) i would have enough oil to do a 3rd oil change for free, less the cost of the filter. For under $70 i can get 18K miles on my current schedule. According to the other post, @ $40 a quart, that would put me at $165+ for an oil change that would last 15K miles. My way is cheaper.

Maybe as time goes on, the cost will come down more, then i would be interested.

BTW ... DB tell me how much you want for that vinyl.

You will still be able to get Mobil 1 at the same price. Its the Mobil 1 Extended Performance that will be more money.
Reason why:
Mobil 1 Extended Performance has a unique formulation with boosted level of protection and performance. These formulations with the Advanced SuperSyn System contain 50 percent more SuperSyn, 36 percent more anti-wear additives, and 37 percent more cleaning agents than the current Mobil 1.

Thats why it will cost a few bucks more!

LavaBox_v1

The new Extended Performance is not $40 a quart. It will retail for about $8 - $10 a quart.

Well, I get free oil changes up to 75k, and they use Mobile Oil. So, I'm going to stick with the 3k mile oil changes till then.

LavaBox_v1

Where did you get that deal at? If you are getting the Mobil Drive Clean (Soon to be changed to Clean 5000) then thats fine. That oil is for your 3-5k changes.

You don't switch to Mobil 1 just for the extended oil changes, your switching for an oil with more cleaning additives, better protection and quality!

Wondered when this would come up. 35,000 is even possible with AMSOIL. My box will have AMSOIL in every form applicable.

LavaBox_v1

If you wanna run AMSOIL for 25k - 35k have fun ... If something happens see how fast AMSOIL comes to your rescue. Call AMSOIL and ask them if you can run their oil for 25k - 35k ... IF they say "YES" then ask them if they will warranty the engine if something happens.

Mobil says 15k or 1 year ... AND they have a warranty for there oil! Read here

Either way, it's still a marketing gimmick by Mobil. They did the same thing many years ago (extended drain intervals), but when they realized people weren't spending as much money, they refuted all claims that said you could go XX,000 miles without changing, and joined the 3k bandwagon to garner greater profits.

LavaBox_v1

This is not just a marketing ploy ... It is stated on the bottle and all the "blue" bottles you see in stores are no longer being made. This is the new line of Mobil and thats it. I had my ExxonMobil sales meeting a few weeks ago and this is in 100% full go with no turning back. Mobil has issued warranties for all the new products and all the new products have been approved by the API and are all Licensed by the API. The commericals are all ready on TV and there is more to come.

Stay tuned for when NASCAR goes to Las Vages, Mobil will be running their three sponsored cars with a NEW paint sceam. Travis Kvapil #77 will be driving the Mobil Clean 5000 Car, Rusty Wallace #2 will be driving the Clean 7500 Car and Ryan Numan #12 will be driving the Extended Performance 15000 Car.

This will be a big year for Mobil and will make or break alot of the other oil companys!

I have run all the top rated synthetics in my various cars.. As a matter of fact I have Mobil 1 in my T-bird, Amsoil in my Volvo , and Royal Purple in my XB now. I have used Redline may times also. All these are good oils. Howver I seem to always get the best results from Amsoil hands down. Being from NJ I had some friends from Exxon who were lubricant specialist and most agree with my thoughts. Some of the Exxon guys invented Millitec which seemed to be a fairly good additive. Any thoughts LavaBox_v1?

Scion05BOPxB

So what makes the oil so much better than the 3k synthetic of the past? What's the difference in the current line to allow for difference in mileage? Just the additives package, or a true difference in formulation that changes how each different products reacts to build-up, thermal breakdown, and such?

In case you haven't guessed, I'm not "on your case" or anything... I'm just the biggest Devil's Advocate I know. It took me about 6 months of research before I even considered using AMSOIL, and I never used it to the full extent of the drain intervals they recommend. I went 14k at one point, and changed it... though oil analysis said that it was ok to continue use.

ThunderGod

well, i better get a hold of my Mobil rep tommorow morning & get my free cases

The new line of oil have been reformulated and new additive packs have been added. Full Synthetic oil was never 3k changes. You regular conventional oil was 3k changes. You could always go more then 3k with synthetic just no-one said anything. Alot of manufactures are now stating that you can go more then 3k. Mercedes Benz has 12,000 oil changes. All their cars use Mobil 1 0w40 its factory filled and its when they use in all their oil changes. Mobil decided since alot the OEMs are stating that you can go longer on your oil changes that they would make an oil and BACK IT 100% to last these intervills. Mobils 5,000 mile 7,500 mile & 15,000 are all back and warrantied by mobil to last thoes miles. No other oil company will make thoes claims and back it with a warranty!
