FI engine oil/tranny fluid recommendations
- Thread starter cmsnake
- Start date
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. *RD30 must be changed every 6 months or 5,000 miles*
8 quart fill – GT
8.5 quart fill – Boss 302 and Track Pack GT
Amsoil ALM 5W-20 – If your car is 100% stock, never raced, driven like a grandma, no matter the climate….use this.
Amsoil AZO 0W-30 - If your car is driven year round up north in very cold temperatures and is lightly modded....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....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 modded to the max and producing HP beyond 600 rwhp, especially E85 fuel engines...use this.
Amsoil EaO17 - This oil filter outperforms any filter on the market.
Amsoil Synchromesh - requires 3 quarts. Use this if you road race your car, or you are experiencing grinding.
If you have the Auto 6 speed, this stuff will make it survive the worst torture.
Amsoil LV Synthetic ATF - 12 quart total fill
and for the rear differential
Amsoil 75W-140 - requires 3 quarts
Don't forget the friction modifier
Amsoil Slip Lock - use all four 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.
