Good capacity and spec info on C5 fills - TTT

TTT ... I did a search on differential capacity ... (yes, Brad & DJ, I'm finally getting around to ordering up fluids & filters).
This is such good info that even if one don't use Amsoil, it is useful :jammin:

Hey Brad,

Thanks for posting this. Also some feed back for you. The tranny fluid worked really well. It had a better feel from the first time I got it up to temperature. You were also correct on the oil pressure rates. The 5W-30 reads the same as the 10W-30 Mobil1 did. I replaced all plugs with magnetic drain plugs so I will be able to tell you more the next time I change everything out. Take care, Don

Ps I hope they are not working you too hard in training.

Myself I like to use synchromech in my T-56 but everything else is amsoil. It's all I sue and all I would use, I've seen what engine wear looks like in most cases with normal fluids.. using amsoil when we went to build my motor it was lookin great. :thumb:

Subdriver -- this is an old thread, so I'm wondering why not use the Amsoil Torque-Drive Synthetic Automatic Transmission Fluid (ATD) for the manual tranny? It says for applications calling for Dextron III. Maybe this is a new product from Amsoil?
This is an old thread... forgot it was even here. I updated all the links and part numbers to their current ones. AMSOIL has updated the oil and air filters to the new EA lines, and also now carries WIX filters including those applicable to the C5 Corvette.

The AMSOIL Torque-Drive Synthetic Transmission Fluid isn't a new fluid. It was back engineered to meet the Allison TES-295 fluid spec. However it also does meet GM Dexron III specs and AMSOIL does recommend it for our tranny as an alternate to the AMSOIL ATF. The ATD is arguably a better fluid as it definitely contains no viscosity improvers and thus may hold up slightly better in the heat than the ATF. But the AMSOIL line, in general, holds up very well under extreme conditions. The two fluids are remarkably similar, which is probably not surprising considering they both do meet Dexron III standards. The viscosities are almost identical, as are the flash and pour points, but the ATF performs slightly better in the four ball wear test.

I have considered using the ATD myself, but never have, partially because the smallest container it comes in is a gallon. However, I guess that is four quarts which is one tranny fluid change.

Either one meets the owner's manual requirements, but I've always felt a little more comfortable sticking with the ATF as that was what the factory fill was. :cheers:

May want to amend Oil capacity with filter, I read the dealers and putting in 7 quarts. I believe the Worm master said so.

Wow ... I would have thought it would be the other way around, the ADT being better than the ATF in the wear department.

Thanks for the info! :thumb:

Thanks Brad. I just updated my spec sheet yesterday when I renewed my preferred customer membership. At the same time I ordered the new air filter EAA83. Information sheet on the new filter is very impressive on the filtering capacity and air flow. Thanks again for introducing me to Amsoil and the great products they produce.

You're welcome and thanks for the continued support. :cheers:

IVO,
The 6.5 quarts vs 7.0 quarts is another controversy worthy of a never ending thread. That stat sheet was cut and pasted off the AMSOIL website last year. Personally, I used 7.0 quarts in mine as well until adding the oil cooler and accusump (which bumped it to nearer 10 quarts).

I was told due to moly ring set I should use regular 10w30 oil only? Any feed back:roll:

Hey Brad,

I have about 60k miles. Is it time to change my fuel filter? I was told 50k-60k miles was good. Is this correct?

Louis,
Personally I don't agree, but I know that there are several major cam manufacturers that recommend against synthetic oils. I don't personally agree with them, but its their business. Some guys will recommend using a regular dino oil for the first oil change with new rings to help seat them in. That is somewhat contradicted by the number of new cars on the market that come with factory fill synthetic. I would suggest you talk to your engine builder and ask why they recommend regular 10w30.

Alex,
I can't find any requirement in my 02 owner's manual to replace the fuel filter. Interestingly, my wife's 03 Chevy Trailblazer does require a fuel filter change every 30k miles. A change in philosophy on GMs part? The fuel filter size on the 02 Z06 is about the same as it is on the 03 Trailblazer (which has the 5.3L V-8).

Personally I think the 30k interval is prudent. I was changing my fuel filter annually as race fuel is notoriously dirty.

Keep in mind that mid-year 2003 the fuel filter moved from the fuel rail (easy to change) to inside the tank and integral with the fuel pump (uh... not easy to change). :cheers:

The new Amsoil SM GF-4 5w-30 has a great additive package and is a better oil then the previous GF-3 version. I've seen numerous used oil analysis reports on www.bobistheoilguy.com and am very impressed with it. I think it's a better value then the 0w-30 Amsoil personally.
