I just hit 2k miles on my new AWD I4 SLT-1 and started wondering about my first oil change. I have seen posts indicating some feel synthetic oil makes a difference in MPG (and maybe performance and engine longevity), but I am on the fence with whether I want to make that committment to synthetic for each oil change. Is it worth it?

Also, I have heard some say that the first oil change should be sooner than you would typically get the oil changed. Should I do it soon or let the DIC tell me when I'm ready?

I am doing mostly interstate commuting with no traffic at 73-74 MPH with the cruise control. My mix is about 70% interstate to 30% mixed city/suburban dring.

If your engine is DI (which yours is) the ONLY oil to go in is synthetic. The extra protection from breaking down and, from used oil analysis's, they are harder to get fuel mixed in as well (the term is slipping my mind right now). DI engines are just harder on oil than a regular FI engine is.


Now, the OLM (oil life monitor) wont know the difference but to me, its totally worth it especially with the deals to be had on good synthetics.

Thanks, that helps. Is there any real reason to choose one synthetic over another or is it pretty much all the same standard? Are any proven to help MPG more than others?

How about doing the first oil change early? Do I need to bother?

See the post by "nuclearboy" under subject "Oil Life System" in the Tech Section for a suggestion. I'm on the exact same page.

Yeah Synthetic is the only option you got! Just read some online reviews or start a poll and go by the popular vote... I use Amsoil.

I did mine early.

I was glad I did because the OEM filter was junk. I changed ours right around 3k.

Search for my post on my oil change for more info. ;)

What about the OEM filter was junk? Mine was perfectly good when changed at 3000 miles.[/color]

Do early for previous reasons. Use Penzzoil Ultra 5w30. (or Platinum). Stuck with the OEM filter (new) Did not have any conclusive evidence for changing to another brand filter. If there is a better one I will change it out. My oem was just very dirty at 2700 miles but not crushed in.

Yea, mine was crushed and the pleats were tearing apart. I was NOT happy with that crap. I really wish I wasnt alone so that my wife could of taken a pic of it.

So, at the end of the day what's the overall verdict...?

What's the best brand synthetic?
What's the best brand oil filter?
What's the best number of initial miles for the first oil change?

Majority wins!

PRODUCT DESCRIPTION
AMSOIL 100% Synthetic 5W-30 Motor Oil (ASL) delivers extraordinary lubrication in all types of automotive gasoline engines. By combining the industry-premier synthetic technology with AMSOIL premium additives, AMSOIL ASL exceeds the higher performance demands of modern engines. It withstands the stress of higher horsepower, higher heat and complicated emission control systems. AMSOIL Synthetic 5W-30 Motor Oil is engineered to outperform competitive conventional and synthetic motor oils. It delivers long-lasting performance and protection.

AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL The First in Synthetics® to do the best job protecting your engine.

Extends Drain Intervals
AMSOIL Synthetic 5W-30 Motor Oil can extend drain intervals far beyond those recommended for conventional oils. Its unique synthetic formulation and long-drain additive system are very stable, resisting oxidation and neutralizing acids. AMSOIL 5W-30 Motor Oil is designed to deliver the best possible engine protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance and waste oil disposal costs.

Maximizes Fuel Economy
AMSOIL Synthetic 5W-30 Motor Oil is designed to maximize energy efficiency for improved fuel economy. Unlike conventional oils, its uniform molecular structure helps it flow more freely and reduce friction between metal surfaces. Anti-friction additives are included to further improve energy efficiency.

Reduces Engine Wear
AMSOIL Synthetic 5W-30 Motor Oil provides outstanding anti-wear protection. It has excellent viscosity film strength to separate metal surfaces and robust anti-wear additives to further reduce wear in metal-to-metal contact regions for improved engine life.

Reduces Oil Consumption and Emissions
Volatility (burn-off) occurs when oil gets hot, causing high oil consumption and emissions. AMSOIL Synthetic 5W-30 Motor Oil has the lowest volatility rate of the oils tested, making it the best at controlling volatility-related oil consumption and emissions (see chart below).

Excels in Extreme Temperatures
AMSOIL Synthetic 5W-30 Motor Oil resists thermal (heat) breakdown better than conventional oils. It is heavily fortified with detergent and dispersant additives to prevent sludge deposits and keep engines clean. And unlike conventional oils, AMSOIL 5W-30 Motor Oil contains no wax. It stays fluid down to -58°F for improved cold temperature oil flow, reduced bearing wear and easier starting (see chart).

APPLICATIONS
AMSOIL Synthetic 5W-30 Motor Oil is recommended for gasoline engines, diesel engines (API CF, ACEA B5) and other applications requiring any of the listed worldwide specifications:

* API SM/CF, SL, SJ ...
* ILSAC GF-4, 3 ...
* ACEA A5/B5 A1/B1
* JASO VTW
* GM 4718M, 6094M
* Ford WSS M2C929-A
* Daimler Chrysler MS-6395N
* VW 503.00

MIXING AMSOIL
AMSOIL Synthetic 5W-30 Motor Oil is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL motor oils.

SERVICE LIFE
AMSOIL Synthetic 5W-30 Motor Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) gasoline fueled vehicles as follows:

• Normal Service(3) – Up to 25,000 miles or one year, whichever comes first.

• Severe Service(4) – Up to 15,000 miles or one year, whichever comes first.

• Replace AMSOIL Ea oil filter at the time of oil change up to 25,000 miles or one year, whichever comes first (other brands at standard OEM* intervals).

• In all non-gasoline fueled vehicle applications, extend the oil change interval according to oil analysis or follow the OEM* drain interval.

*OEM – Original Equipment Manufacturer

(1) Engines operating under modified conditions(non-stock) are excluded from extended drain recommendations. Examples include the use of performance computer chips; non-OEM approved exhaust, fuel or air induction systems; and the use of fuels other than those recommended for normal operation by the manufacturer.

(2) Mechanically sound engines are in good working condition and do not, for example, leak oil or consume excessive amounts, are not worn out, do not overheat, do not leak anti-freeze and have properly working emission control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL synthetic oils.

(3) Personal vehicles frequently traveling greater than 10 miles (16 km) at a time and not operating under severe service.

(4) Turbo/supercharged vehicles, commercial or fleet vehicles, extensive engine idling, use of AMSOIL motor oil in vehicles with more than 100,000 miles without prior use of AMSOIL motor oil, daily short trip driving less than 10 miles (16 km), frequent towing, plowing, hauling or dusty condition driving.

AMSOIL Ea full-flow oil filters are designed for extended drain intervals. They stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL full-flow oil filters.

Amsoil looks great. How much are you paying? I try to keep in mind the cost vs. benefit ratio over the effective lifespan of the vehicle. Does anybody have any empirical experience with Castrol Edge synthetic which claims 8 times more wear protection of Mobil 1?

The best will always be synthetic and ANY brand will be better than using non-synthetic...and the poorest brand synthetic will be good enough.

The more important factors are cost and availability...with both oil and filters.

My own personal choice is Amsoil ASL oil and Wix filters. Wix only because as of yet Amsoil doesn't make a filter for the I4 Terrain. If Amsoil isn't available or if the cost puts you off I would use Valvoline, Castrol, or Mobil 1...probably in that order.

Something else to consider is when to make the change to synthetic. The rings are not the only things on an engine that need to be broken in and if you switch too soon things like bearings will take longer to wear in. My own personal regime on a new car is to change the oil at 500 miles...yes you read that right 500...then again at 3000. On the third oil change (whatever mileage that happens but normally 6k to 7.5k) then I make the switch to synthetic.

You can use synthetic right from the get go and you won't hurt anything but it will take longer for the engine to be fully broken in.

^how do you know if your theories re when to switch to synth are correct? Oil analysis? Are you a chemical engineer? Or just flying by the seat of your pants?

I got that advice many years ago from someone who rebuilt engines for a living. He also had a very specific break in ritual (which can be found if you search my posts). I've personally used his advice on five vehicles and know of 4 or 5 times that many that were done the same way.

Several of those cars/trucks have well over 100k miles and one I know of has over 300k. The 300k+ car is still getting better than EPA rated gas mileage.

But like I said...it won't hurt anything if you switch to synthetic before you even drive off the lot for the first time - it will just take longer for the engine to be completely broken in. That's why you'll see posts saying their vehicle "finally" settled down and felt like it was completely broken in at 10k-15k or more miles.

I use regular oil. As long as the oil has the API starburst and the proper rating (I believe that SM is the highest standard now) you are fine. GM has it's own standard which is in the manual and would also be listed on the oil container. I use whatever is on sale. On my 10 year old Saturn LS1 I have used Wal-Mart oil (Mostly walmart but other brands when on sale) and have never had to add any additional oil and the car has 116,000 miles and runs fine. My 1993 I used regular oil and had 140,000 miles on it when I sold it with no problems. Synthtics are better but engines are just fine with regular oil. I use this anology .. Gold is the best conductor of electricity but Copper does just fine.

I picked up 3 - 5 gallon jugs of regular Valvoline on sale for when the next changes have to be done on the Nox. I have a case of AC/Delco filters. I'm a low mileage driver but do my changes every 3 - 4 months

Again, for the price difference in syn and regular oil, Id HIGHLY, HIGHLY suggest getting the extra insurance with the DI engines. Go to bob is the oil guy forums and read up on how hard DI engines are on synthetic oil to make up your mind on what to use.
