I'm going with AMSOIL. #1 in independent lab tests. 1 year 25,000 mile in or out of warranty change interval guarantee.

please tell me you're not going to do a 25,000 OCI. amsoil and schaeffers are always the best, Sarge has gotten better results with schaeffers and it is only $4.65 a quart

That is what will be going in my T/A once I can find a good shipping deal. No dealers within 100 miles of me though.
Until then, 10w-30 Pennzoil Platinum. That is what the daily driver gets every 5K.

As for the oil change intervals....I change twice a year in the T/A....regardless. Spring and fall. Normally 1500 miles between changes.

I'll give it a look see. I only drive the GTO about 5500 miles a year so I'm only planning on doing one change a year. Weather changes aren't that extreme down here.

PP it is then...great! thanx, kids!

**MotorDogStar** · 06-29-2009, 07:05 PM

but why 5.5 or 6 quarts?....will 5 not due?

**MotorDogStar** · 06-29-2009, 07:10 PM

also...once I change to Synthetic I can't switch back to regular oil right?....like if I had an emergency and had only reg oil around.....

**HOBS** · 06-29-2009, 07:46 PM

It takes 5.5 quarts so you have to buy 6, 5 for the engine and .5 for the filter if I'm not mistaken. Its generally not a good idea to bounce back forth between sythetic and regular causes leak issues that nobody wants to deal with. Also for my .02 I run 5w-30 Royal Purple full sythetic with a Mobil 1 filter, cant remember filter number, best oil IMO but its expensive if you dont have an in at a parts house.

i run a full 6 quarts, everytime even before i ran the larger filter it always came up short on the stick. also ditch the royal purple, pennzoil platinum will make your engine very happy

Many people meeting the “normal service” criteria listed below have posted good Used Oil Analysis (UOA) results after doing the Amsoil 25,000-mile/1-year Oil Change Intervals (OCI). Amsoil's top tier synthetics are formulated for extended OCIs and it is possible in some applications.

That said, read the recommendations first before doing an extended OCI. Also, as mentioned before here in the forum, the safest way to extend oil changes is based off of UOA findings. You don’t want to find out the hard way that your air induction system is leaking dirt, or you have excessive fuel dilution, or a coolant leaking head gasket, etc; all of which will reduce the service life of the oil very quickly.

Amsoil Extended Oil Change Interval Recommendations:

SERVICE LIFE

AMSOIL 100% High Performance Synthetic 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.

Personally, I wouldn't run Pennzoil in my lawnmower I just don't think its a good oil never have never will. Its plenty happy with Royal Purple BTW
