what kind of oil?
- Thread starter TXSVT1
- Start date
here is what i use. the best oil I've ever used. i change it every 10k it can go to 15k....before changing....
AMSOIL SAE 5W-20 Signature Series 100% Synthetic Motor Oil
AMSOIL SAE 5W-20 Signature Series 100% Synthetic Motor Oil
I just run Mobil 1, I swapped to Royal Purple throughout my truck last year and no noticeable difference in anything. I don't do oil samples though.
how do you get away with 5w20 on a blown motor? I thought 10w30 was best for that.
I switched to Amsoil Signature 10-30 when I installed the TVS. Its the real deal!
I used SS 10w30 Amsoil when I was on gasoline, now I run 10w30 Dominator Amsoil on E85.
For plugs while you are N/A stick to the stock motorcraft.

What's the real difference between 5-20 and 10-30 other then the viscosity? People say 10-30 is better but where's the evidence?
Depends on your climate.
I would use 10w30, but unleashedbeast would know best.

I will post the master recommend list first thing in the AM.
using 5W-20 Amsoil Signature Series.. I love this oil.. But I'm also wondering if the 10W-30 SS oil from Amsoil would offer better protection?
Using Amsoil 5w 20 and I called about every person there was to call to ask about what oil to run with the TVS. Everyone of them said stay with the 5w20 even with the blower , I called Ford Racing, the Ford dealership I bought my car at, Amsoil, Roush, The Shop That Put My Blower on...etc etc you get the point but they all said stay with 5w20 and use either Amsoil, Motorcraft, or Mobil 1. I'll be changing every 3 thousand miles anyhow with the blower.

Why the difference?
This recommendation list will cover all seasons for your car, from the harshest winter days, to the hottest summer days. The best part is, the oil only has to be changed once a year, or 15,000 miles, whichever occur first. Amsoil RD30 excluded.
8 quart fill (Coyote GT)
8.5 quart fill (Track Pack GT & Boss 302)
Amsoil ALM 5W-20 – If your car is 100% stock, never raced, driven like a grandma, or short tripped, no matter the climate….use this.
Amsoil AZO 0W-30 - If your car is driven year round up north in very cold temperatures, is lightly to moderately modded, and street or drag raced frequently....use this.
Amsoil ATM 10W-30 - If your car is moderate to heavily modded, used in hotter climate states, or never driven during winter months in northern states...use this.
Amsoil AMO 10W-40 - If you have a Boss 302 or Track Pack GT, and you road race your car for extended sessions....use this.
*Boss 302 and Track Pack GT owners - If you do not road race your car, use Amsoil ATM 10W-30. 5W-50 spec for this engine is overkill and results in excessive oil pressure.*
Amsoil RD30 10W-30 - If your car is heavily modded, producing HP beyond 600 rwhp, especially E85 fuel engines...use this. This lubricant must be changed every 6 months or 5,000 miles, whichever occur first.
Amsoil EaO17 - This oil filter outperforms any filter on the market. The Royal Purple 20-500 is the same oil filter.
If you have the Getrag MT82 6 speed manual
Amsoil Synchromesh - requires 3 quarts. Use this even if you road race your car, are experiencing grinding, or simply want the smoothest shifting possible on the street.
If you have the 6R80 automatic 6 speed, this lubricant will help it survive the worst torture, lower internal friction, and reduce heat.
Amsoil LV Synthetic ATF - 12 quart total fill *With a torque converter swap, you will not need more than 10 quarts if you do not flush the external transmission cooler.*
and for the rear differential
Amsoil 75W-140 – buy 3 quarts to insure you always have enough no matter what differential cover is installed
Don't forget the friction modifier *Ford XL-3 is another great option here*
Amsoil Slip Lock - pour in 2 ounces (half bottle). If the differential still chatters, use the remaining two ounces.
*Boss 302 and Track Pack GT owners. If you have the Torsen differential in your car, do not use friction modifier.*
Bottle Hand Pump - makes pumping new fluid into the transmission and rear differential very easy.
UOA testing kit - we have dedicated UOA threads to compare everyone's reports.

Last thing, do NOT pay retail for Amsoil...EVER! This is how to buy all Amsoil products at wholesale cost (saves 25% off retail).

Dominator is a racing formulation that has enough TBN (detergent additives) for continued street use. It's high in ZDDP and the most aggressive anti-wear package that Amsoil offers for high HP engines that are well outside their intended design.
You can see from my list above, it's recommended for cars that are tuned to the edge and high in HP. The down side is more frequent oil changes, but in my opinion, it's more than worth it.
*more frequent when compared to other Amsoil formulations that only require once a year oil changes*

What about Royal Purple? That's what I'm running. But this is my "keeper" Mustang that I have no intensions on getting rid of I want to make sure I can get as much longevity out of it possible. Is my current oil good enough or are you saying Amsoil is that much better I should switch? My engine is stock for now but I run her kinda hard sometimes.
