OK...first off I know everyone has there own favorite brand of oil and their own reason behind it. Second, I have no need or interst in an oil that can go 15,000-35,000 miles between changes. I live .5 miles from work, I drove just 5,000 miles last year! I AM a gas saver, not my truck!

So, it comes down to Mobil 1 5W-30 or AMSOIL XL7500 5W-30. With the few miles I put on, I will only change it once, maybe twice a year. I live in Iowa, so we get plenty hot and cold weather....I might change oil between seasons just because.

Mobil 1 goes for about $6 per qt. When AMSOIL is on sale, it goes for about $4.50 per qt. There is an AMSOIL dealer in my town as well so I could get it from him. Not sure what Mobil 1 goes for if/when on sale. I can get quality Fleetguard oil filters from the place I work at. So, it just somes down to the brand of oil.

Both are great....but I like to here what others have to say. Thanks.

the XL7500 and mobil1 are about the same, quality wise

 

wish my round trip was 1 mile a day. i drive 52 miles roundtrip.
i started to put mobile 1 full synthetic in mine. will change the oil every 10k

 

ride a bike... i think bob answered teh question but the only thing is, how many times is the AMSOIL on sale...?

but really, my brother is moving like 3 miles from his work and he got an old scooter from a freind and is fixing it up really nice so he can jsut bust that thing out and go to work...

 

.5 Miles, you don't want synthetic.

Synthetic needs to get hot to "boil" the water out.

 

Thomas where is the data to support that?
I would think that water would "boil out" equally
for syn. or dino?

The amsoil xl7500 is if I remember a group III oil more like
castrol syntec a "hydrocracked syn" not a PAO syn like normal amsoil
or M1 syn.

Personally If you arent going more than 5000miles the 1.47$ per quart
trop arctic by phillips is a Group III oil too. Its made by philips conoco.

Edit: double post.

 

The amsoil xl7500 is a decent oil that is comparable the the mobil-1 product. If you are looking for gas milleage, I would recommend using the amsoil 0W30 and there new EA series filters. The oil is rated at 35,000 miles and the filter at 25,000 miles. I understand that you do not put that many miles on, but paying a little extra for the better oil may save you some $$$ in the long run being that the 0W30 is a more fuel efficient oil.

If it helps, I am an amsoil dealer. I sell there products at dealer cost, nothing more. Whatever an order cost for me to have it shipped to my house is the same price that you would pay to have it shipped to your house. The only extra charge I have is an extra amount to cover any paypal fees if you choose that method of payment. That amount is usually approx. $1 for every $75 on any order. If an overpayment is recieved, I will return it back to you through paypal. I do not make money on the amsoil product, I am just trying to get the product out there. Word of mouth will do the rest. This offer is only available for people on this site. If this site is not mentioned, full retail price will be charged.

 

haha, too many amsoil dealers on the site ive been dealing on here for a long time now

 

Synthetic does not heat up as quickly. You need an oil temp of at least 190* before you see any benefits of synthetic. Ever tear apart an engine and find all of the white "snot" around the cam? That is water from oil that has not gotten hot enough.

 

I use Mobil 1 5w-30, and a Motorcraft filter

 

Well mine is 2.6 roundtrip or 5.2 if I go home for lunch too. You should work closer to home.

 

1)How does one oil not heat as fast as another?

2) Amsoil XL series is a group III hydrocracked syn.. not equiv to m1 as far as basestock. M1 is a PAO like amsoil's normal series oils.

 

I will admit it is nice to live so close to work. Still, the gas I save Monday-Friday I tend to burn up during the weekend. It does cut down alot on miles.

I do ride my bike to work sometimes during the summer. Helps keep those extra pounds off.

One of the "benefits" of synthetic is that it does not heat up as fast or as high of a temperature as dino.

 

Thomas... I really dont' have to many positive comments about your statements, besides, everyone has their own thoughts. What you are saying is partly true, but mostly false. However this is a whole different topic then what is going on in this thread, so I will not go on here.


As to the topic. Both oils are very good, AMSOIL does have a slightly upper hand in the comparison. Driving only .5 mile to work everyday puts alot of stress on your motor and all other parts of your truck. This holds the most true during the winter months. As the weather gets colder and the oil does aswell, the oil will thicken up and offer less protection. This is true for all oils, AMSOIL and Mobil 1 included. So things that are important in your case, is not the 25,000 mile/12-month change intervals, it is going to be these numbers that intrest you and that should play a huge part in your decision:

AMSOIL 100% Synthetic 5W-30 Motor Oil (ASL)
Pour Point °C (°F) (ASTM D-97) = -51 (-60)
CCS Viscosity @ -30°C, cP (ASTM D-2602) = 5254
Kinematic Viscosity @ 40°C, cSt (ASTM D-445) = 57.3

Sorry I don't have Mobil 1 information here. But I can tell you that these numbers will beat out all of Mobil 1! And we are proud of that here at AMSOIL!

Here is another small chart that will show you the Evaporation/Volitility of AMSOIL along with some of it's compitition. You will notice that AMSOIL and Mobil 1 are by far the leading edge.



Being the first on R-F with AMSOIL (Passed most of the R-F business on to Bob (SOUNDPER4MANCE)), and the only T-1 Certified AMSOIL Dealer on this site. I am pretty comfortable with how AMSOIL works and the different advantages it has over Mobil 1.

 

I have no problem with amsoil being superior to M1 just amsoil XL series being equiv to m1.

Also Thomas those comments are pretty close to being all false.
If you can find some site or source that backs that up please post it.

Syn oil heats up the same as Dino.. its just more resistant to breakdown
and can take more heat. I suspose you could argue about friction but
its not friction heating the oil its the gas burning. Motor oil is really too thin
to significantly warm up from friction in the time it takes to warm up.

 

ummmm...like I said before, oil preference is really one's own choice. Since I drive so few miles daily, I know my oil does not warm up much at all. I want to use the best oil that I can buy due to my driving habbits.

WholsesaleMN and Rand, thanks for the info and input.

I had another idea. I could run John Deere oil 5W-30 Plus 4 ($1.95 qt.) and John Deere filter ($3.95) which I can get at work and just change it more often.

Moisture buildup seems to be the biggest problem. I hate it when I change oil in my wifes car and the bottom of the oil fill cap it covered in white snotty goo.

AMSOIL Keeps Your Engine Cooler: The superior lubricity of AMSOIL reduces lubricant temperatures by 20 to 50? F. AMSOIL retains its protective film at engine temperatures that destroy regular oils. AMSOIL synthetic lubricants keep equipment running cooler and safe in the hottest temperatures and severe conditions.

From a quick google search. Now, here is some information on condensation, yes it says marine, it is still the same principal. http://www.syntheticwarehouse.com/marine.htm

http://www.motoroilbible.com/two.html

"Another part of cold weather driving that is extremely tough on an oil is condensation. Because it is so cold, it takes a fairly long drive to get the engine warm enough to burn off the condensation that occurs inside the engine. As a result, vehicles routinely driven short distances in cold weather will build up condensation within the oil. If left to do its dirty work, this build up of water would cause acids to be created within the oil and corrosion would begin within your engine. "

The next paragraph talks about how there is more additives in synthetic to combat the rust issue. With synthetic running so much cooler, it would have to have more additives.

Those with oil coolers, this is the thermostat to use, IMO. Jegs has them for around 30 bucks.

Don't get me wrong. I am not saying synthetic is bad for all engines. When you drive a mile a day, you are doing more harm than good, no matter what oil you use. Synthetic can be very beneficial. It needs to reach opertaing temperature before you see any benefits.

Also, driving a mile to work a day works out to what, months on a tank of gas?

 

nevermind.

 

One tank of gas could last at least a month, but I tend to go places on the weekends. In the summer I am gone almost every weekend with my buddy who races ATV's in the Iowa Hare Scramble series as well as a few GNCC races. I tend to do the pitting/wrenching work when I can.

So ...for the most part, Monday-Friday my oil will be cold and will be hot Saturday/Sunday. I think synthetic oil still is a better choice, even more so if I hook onto our trailer.

my company moved to a bigger location. 13 miles further away from my house. why should i move closer just because they didnt want to renovate the old warehouse?

 

if you want the best oil/filter available, go with the amsoil 0W30 and there new EA series filters. You can view both at the links below.
