Gonna Change to synthetic oil....Amsoil 5w-20 or Mobil1 5w-30
Hey everyone. The 2003 CLS I recently bought has aboutt 11k on the car. I decided that I want to change it over to synthetic. I have ready MANY of the previous posts here about oils and there is a lot of good info. BUT, I live in florida, and I want an oil that will protect in the hot weather but also an oil that will still give good performance. I used Mobil1 on my previous cars but they don't make the correct formula (5w-20) for my car. That is why I am considering Amsoil. I know both are superior oils and some the Amsoil is better. What I am asking is that is it better to have the correct weight/weather formula that is required to put in your car (I know they changed the oil for the 2003 CLS), or to put a slightly thicker oil that might protect better than thinner oil eventhough they're both synthetics?

Blackbird baby..
The 0w is for the CAFE standards.. don't use it. I have used both Amsoil and M1.. Both are equivalent, imo. My recommendation is to get the gallon jug from WalMart, in 5W-30 and run that. The key is to get a good filter.. I use the oversized Mobil 1 one, and there's others that are good as well. I think Purolator makes a good one too.. There's an oil filter FAQ--check it out.
In my opinion the Amsoil is decent but isn't that much better than Mobil1 to warrant the incovenience of buying a reseller account, ordering it online, paying shipping, waiting, etc.

Amsoil is big on extended drain intervals,,, change filter every 5k and by analysis you will find amsoil will last over 15k miles... if you want to change oil and filter every 5k use moble1. I have built up confidence in amsoil products only after many lab tests.. I use 0w30 and change oil every 10k miles (5k on filter).. this is still very early in the oils life.. much emotions on this subject exists. Also there are many people like myself who sell amsoil out of our trunks at a little above wholesale just to cover all costs,,, ask around in your town they are out out there.

Sounds like i'm gonna go with Mobil 1 5w-30....as for the oil filter. I looked at the Mobil 1 filter for my car and it is tiny!! I know that everyone says to go with the M1-105 instead of the 104. Well, I looked at both of them and the 105 looks wider but it's not really taller. Am I looking at the right one? Also I looked inside and there is a spring mechanism that is visible in the 104 but the 105 doesn't have one. Can anyone shed some light on this?

At that time the engine was using only 1/2 quart of oil between oil changes! Now that my 2001 CL-S is out of warranty, I will be switching to a 10,000 mile oil/filter change schedule on it also.

When I can get the Amsoil delivered without offering a stack of Krugerrands,
or pick it up at the same stores I get the Mobil-1, I'll be changing my tune

My friend told me that many people across different boards have complained that Mobil 1 is not a true synthetic oil compared to the rest of the market. Can anyone else verify this ?

I personally use 0w-30 Mobil1 with a Wix filter. Wix filters IMHO provide the best filtering I have ever seen. I may switch to 5w in the future due to global warming

From Mobil1.com
What is Mobil 1 and why is it now called Mobil 1 with SuperSyn?
Mobil 1 is a fully synthetic motor oil for automotive engines. It is made from a unique combination of high-performance fluids, including polyalphaolefin (PAO), plus the SuperSyn anti-wear system for protection under the most extreme use. Mobil 1 with SuperSyn is available in five viscosity grades:

What is the benefit of using the M1-105 over the manual recommened size of 104?
And I use Mobil drive clean 5w-20 and change it every 3750 miles just like the manual states. In Michigan we have a wide range of temperature changes, even in one season, so an extended interval isnt the best idea due to condensation buildup.

Amsoil is based out of Duluth MN. A lot of extream temps there.

Senor Fendór,
While I actually do like what Amsoil is doing in the engineering arena, I've commented about marketing "funnies" that they do. Here is an example of something that has nothing to do with the fine oil they make, but I keep talking to people that wonder about stuff like this:
![](http://www.amsoil.com/performancetests/amsoil_vs_mobil1/pourpoint_200.gif)
Personally, I find this insulting to my intelligence. (The difference between the two looks to be twice as great if you just take a casual glance at the length of the bars).
The bar graph trick is getting pretty old. What's next? Showing a 2-foot long bar if the change in pour-point temperature is 0.25 degrees F.

Engineering excellence combined with some kind of deep-seated insecurity perhaps?

I agree and wish they would pull this temp chart,,, what has me concerned is the TBN number in the "8"'s I have seen mobil1 in the 12's ,,, mobil is somehow decontent quality thru manufacturing,,, this is bs from mobil. also amsoil is fighting the battle of mobil claiming they are the best. By which tests I don't know but they are very good marketeers,,, again when it comes to advertising anything goes,, science is out the window..
