Tune up

[Nightrage]

My car is getting a tune up on friday. My plans are-

Switching to Royal Purple Synchromax for the transmission (I'm buying 5 quarts) and Max Gear (3 quarts)for the differential. That should be more than enough fluid to fill each, I hope.

I'm going with NGK TR55 plugs. The iridium ones (ITR4A15) as I've read on this site that they last nearly 100k miles. I'm also going with Taylor plug wires. I hope the plug wires last as long as the plugs

Is there anything wrong here, or does everything sound about right? Should I do something differently, wrong parts/ bad combinations, anything? Thanks guys

Is the Synchromax an approved substitute for the Dexron II/Dexron III speficied for the T56? I've had good luck foro 13 years without using extremely high priced lubricants. If you had a 1,000HP monster, it might make some sense, but they are expensive overkill on a basically stock setup.

Rather than just guess at the quantity of fluids required, why not look in your Owner's Manual for the correct amounts? If you don't have an Owner's Manual, Shoebox has a link to online copies on his website.

I don't think anyone has been running Iridium plugs long enough to know how long they last.

They state on their website that Synchromax is what should be used in place of Dexron III. Also, The tranny takes 3.8 liters and the differential takes 1.7. I believe Royal Purple's quarts hold .94 liters, which should work out to be the numbers I have. 3.8 liters would take a breath over 4 quarts, so unfortunately, I need to buy 5. 1.7 works out to be just under 2 quarts, so I guess I would be safe if I only bought 2 quarts. Thanks Fred You just saved me $10

Some people are telling me not to use synthetic in my rear as it's an Auburn rear. I have no idea why. They said not to use synthetic in the transmission either. There's an equal amount of supporters on each side. I'm lost here.

I double that .04 liters is going to make a difference (Save yourself the $$). You will be fine with 4 quarts. I would Run Just some Dexron III Trans Fluid. Your not going to get anything else by spending the extra $$ for synthetic. I run that Pennzoil Dexron III which according to Pennzoil, It recommended for GM motors. In the rear Just use your standard Gear oil. Your Pretty much Stock so You'll be fine. Spend that money on Synthetic oil for the engine.

Its better to have the 5th quart on hand should you need a little extra down the road than not. Go with the 5th quart. As for using synthetic fluid in the tranny, that's up to you. Some have said to use B&M Trick Shift in the T56, some say to save your money and just use standard Dexron III ATF. That's a judgement call. As for the rear, some have good luck running synthetic gear oil with an Auburn diff., some not. That's entirely up to you. The claim against the synthetics (as I recall) is that they do not stick to the clutch packs in the actual diff. like regular oils do, even with the LSD additive. And I would sure hope you're using a full synthetic motor oil already . If not, sounds like a good time to make the switch. I've been running Royal Purple for years and love it. The motors run better, get better mileage and the turbo in the GN seems to spool up just a bit quicker (and its more noticeable audibly ).

If it were me, I'd run RP motor oil and tranny fluid, but I'd be wary of the gear oil. Hope this helps dude

I ordered Royal Purple gear lube and differential fluid. I guess we'll see how it goes. I've been using Mobil 1 motor oil. You think Royal Purple is better?

[MunsonGTA]

RP usually doesn't work good in anything that is clutch based, such as your LSD and your transmission.

Correct me if I'm wrong, but since when does a T-56 have any clutches inside the assembly?

As for Royal Purple vs. Mobil 1 motor oil, it depends on who you ask. Personally, I prefer to run RP as it is a true synthetic (Class IV) vs. a high-grade, petroleum-based "synthetic" (Mobil 1 is a Class III oil from what I've read, which is not fully synthetic). However, I have not used Mobil 1 in any of my vehicles so I do not know what the fuel-economy difference or the performance difference would be.

When I had the intake vacuum seal fixed, the mechanic replaced the oil with regular oil and never told me. I wound up finding out through my stepdad after I had driven about 1,500 miles with regular oil in it. I never noticed a difference in fuel economy. Same thing when I switched back to Mobil 1. My fuel economy stayed the same.

Then I would say to give RP a shot and see what you think. You may just like the results...or you may not notice anything at all lol. I've noticed it in all 3 vehicles myself.

i didn't see that he had a t56 in his car. i was refering to automatic cars.

What oil filter do you guys use? I use Fram

[Z Ya Later]

K&N filter here on all 3.

[97Bandit]

I used to work at a parts store and we tore open three different filters fram is the cheapest made and uses the oldest technology filter wise...and the best one made at our store was a wix filter it has a very good quality, napa gold filters are just wix filters in napa's box.

I too Have been using Royal Purple and like it, not only i know its a good lube but as hard as i drive my car i want the best stuff i can put in it. so when i pull up to the stop light i know shes still ready to go lol.

Yea though i would run a fram on anything i own unless it was just a cheap vehicle.
