i have a 2005 2.2 base coupe cobalt. and i had the dealership do my last 2 oil changes because when i bought the car the salesman got a couple freebies for me and now i dont ahve anymore and i am going ot start doing it myself considering it only takes maybe a half hour and it is cheaper. so i was wondering what type of oil and filter i heard acdelco is the way to go on the filter and royal puple mobil 1 maybe even castrol syntec were te winners for oil please help i dont know and i know to use 5w-30 and some places recommend 0w-30 i read the how to oil change but thats for supercharged ss could anybody help me!!! please

 

I use mobil one, I swear by thaat stuff, although royal purple is good stuff to i heard

 

i use mobil1

 

I wouldn't use Castrol. This thread tells why:https://www.cobaltss.net/forums/show...ht=castrol+gtx

I know it talks about Castrol GTX and not Syntec, but if GM bans them, so do I.

 

i use mobil 1

 

I switched from Mobil 1 to Royal Purple after I heard about Mobil 1 not being 100% synthetic anymore. Plus I can get Royal Purple cheaper for some reason. I'm running the K&N oil filter this time, so when I go to change hopefully it won't have as much crush as the AC Delco filters do.

 

I use stp filters with mobil 1, but i think im gonna switch to amsoil

 

what about the eneos oil i heard thats the best oil

 

im switching to amsoil now that my buddy is a dealer for them

 

I usually use Qhorsepower, been using it scense my 1st oil change back in September of 07.

 

Yes, Castrol sucks. There is lots of proof that it is junk.

The problem with Mobil 1 isnt' that it isn't 100% synthetic anymore... it is that they switched the regular Mobil 1 from a group 4 base stock to a group 3. I use the extended life Mobil 1 which is still made from group 4 base stock.

Amsoil and Royal Purple are both good oils to use, and both made from group 4 base stock.

 

i use mobil 1 in my HEMI and Amsoil in my monte SS

the amsoil you can run for 12months or 23,000 miles ( not a typo)

 

what????

 

I use mobil 1 also

 

SuperTech Fully Synthetic 5w30, sold at walmart at 3.50 a qaurt or $15 for a 5 quart jug. Made by mobile 1, just half the price cause its at walmart

 

oh yeah, and if you want you can send in an oil sample in intervals and have it analized for 10 bucks

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 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, first and subsequent use of AMSOIL in vehicles with over 100,000 miles, 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.

^holy crap

 

Amsoil is pricy, for 10 qts (7 for the monte and 3 for extra) and the filter, ran right at 100 bucks, but they guarentee there product for like 100,000 miles if you engine grenades and you can prove its was do to sludging or oil related, they will pay IN FULL to repair/replace.


And in the Hemi Ram, i use mobil 1 because ams doesnt make 5-20 yet and i run an amsoil filter, you can see the difference at oilchanging time.

 

I was just checkig out the Amsoil before you posted that up.....that's pretty damn impressive, I may be switching.

 

we put royal purple in my wifes 2.2 and just a fram oil filter. her 2.2 opens right up after you put in the RP. id recommend it anytime

 

did you see that it is 15,000 or 1yr on turbo/sc cars.

see clause 4

 

yeah, but hell...a conservative 12,000 would be awesome, with maybe a filter change at the halfway point

 

That thread you linked to was a real comedy.

BTW Castrol GTX is back on GM's approved list.

 

pennzoil is not bad at all...a good alternative for mobil 1. Don't run Q...it's garbage.

amsoil makes filters? doubt it for the 2.0

I don't think it's the same as mobil 1 anymore. They did some sort of analysis and it doesn't look the same. In fact they say it may be recycled oil...um...bad news.

Brands I want to try but am too lazy to track down: Torco, Greddy, Motul, Redline, (does lucas make 5w30, then them too).

Anyone with a 2.0 use oil additive for a quart?

 

Yeah, SuperTech uses whatever oil they get cheapest at the time. Could be from Mobil, could be from Pennzoil, could be recycled. It is just as bad as Castrol and I wouldn't trust to put it in my car ever.
