Thinking about switching oil

[Pontiacman]

Hey guys I am looking at maybe changing oil. I have an 05 with 44000 miles on it, and been running m1. I don't have any plans for mods and wanting to change to something cheaper. I just want something that is going to do a good job.



Thanks guys
Clint

I use valvoline fully synthetic, Walmart almost always has a good deal on it.

I sell amsoil at good prices on here, hit me up if you need some.

I agree AMSOIL is the way to go...

[Pontiacman]

Thanks for the replys. Can I have longer change intervals with amsoil than with mobil one?

[mark1970]

yes, but please read the following info on the amsoil site here: https://www.amsoil.com/storefront/atm.aspx

I normally recommend what amsoil says 25k or 1 year.

from the amsoil page:

SERVICE LIFE
AMSOIL Synthetic 10W-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 full-flow oil filter at the time of oil change up to 25,000 miles or one year service life, whichever comes first (other brands at standard OEM* intervals).
• In all other 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 manufacturers.
(2) Engines are in good working condition and within the factory design settings. Mechanically sound engines, for example, do not leak oil or consume excessive amounts, are not worn out, do not overheat, do not have internal or external anti-freeze leaks and have properly working emission control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL synthetic oils.
(3) Personal transportation 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, excessive engine idling, use of AMSOIL engine oil in vehicles with over 100,000 miles without prior regular use of AMSOIL engine oil, daily short trip driving (less than 10 miles), frequent towing, plowing, hauling or dusty-condition driving.

So with that info: i would and use the 15,000 mile or once a year change schedule... but you can also sample you oil and have it tested to know exactly how far you can go on a change... the kits are available from amsoil and are quick easy and inexpensive.... https://www.amsoil.com/catalog.aspx?GroupID=683

I don't think M1 is that expensive, especially when picked up while on sale at Advance.

Thanks for the replys guys. I an still stuck on what I want to do,lol.

Well I have read the info on amsoil and like what I see. I have come across a few forums were people cab run a bigger oil filter than what is recommended. Is there anything special to doing that? And what would be a good oil filter if I decide to go with an extend performance oil?

[TheOtherNick]

You use a filter for a 4.3l blazer. You dont have to do anything special to use it, your car will just take .5qt more oil. I recommend the amsoil filers if you are going to be using their filters.
