Oil for Vortech Coyote?

[WIST2013GT]

Looking for advice on what weight of oil I should run in my vortech car. It gets driven a few days a week to work and sees the track maybe once a month. There are a lot of threads about this, but most of them end in arguments and never actually state good choices.

Based on the above, 10w30 seems pretty common. Does anyone agree/disagree?

Thanks.

I was thinking something a little thicker to help protect the OPGs.

This is a newly revised application list I have created and is simplified to make the choice easier. 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 AZF 0W-40 (Challenger Hellcat and Nissan GTR) and AMR 5W-50 (Ford Mustang) are two new formulations created for powerful street cars.

8 quart fill – GT
8.5 quart fill – Boss 302 and Track Pack GT

Amsoil ALM 5W-20 – If your engine is 100% internally stock in Naturally Aspirated form, regardless of external simple bolt on mods, driven daily in all climates, use this. *Mustang GT only* previously, the old list recommended formulations in the 0W-30 to 10W-30 range for this engine. However, after testing in my personal 2014 Mustang GT with a stock engine, 5W-20 Signature Series is a contender. Using previous recommendations is OK, but will now use AZF 0W-40 as the blanket for most application requirements beyond 5W-20 for simplicity.

Amsoil AZF 0W-40 - If you have a Boss 302 or Track Pack GT and you do not attend HPDE events, use this. Some people ask me if it’s OK to use this at the HPDE. If you plan to attend one event a year and are not driving the car to the edge of cooling limits, it’s acceptable. Schedule the annual oil change to happen right before the event to insure the lubricant is fresh. However, if you are an experienced HPDE track person, 5W-50 may be better suited for you. See the recommendation for 5W-50.

Amsoil AMR 5W-50 - If your street car has a single/twin turbo or supercharger making a lot of power on pump gas or with advanced timing using E85 (or) If you have a Boss 302 or Track Pack GT, and you HPDE or race your car in competition for extended sessions….use this. *Not optimal for short trip, grocery getting, daily driven street duties. If you have a turbo or supercharged car that is driven daily, isn’t raced frequently, used on the streets for occasional wide open throttle bursts, Amsoil AZF 0W-40 is a better choice.*

Amsoil EaO17 - This oil filter outperforms any filter on the market for the Coyote/Roadrunner. Royal Purple is the same filter, part # 20-500.

Amsoil Synchromesh - requires 3 quarts. Use this if you road race your car, or you are experiencing poor shifting.

If you have the Auto 6 speed, this stuff will 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.*

Amsoil Fuel Stabilizer - Use 1 ounce per 2.5 gallons of gasoline when storing your car in the winter.

Bottle Hand Pump - makes pumping new fluid into the transmission and rear differential very easy.
