Have you guys ever heard of Schaeffer's oil? They been around since 1839 , and I would say its like Penn oil but better. It looks like Penn oil because it may be coming from the same green base oil.
I have been using their oil for the last 4 years and wont switch back to any other brand.
You will find some Blackstone reports on the web for 20/50 for the oil if you have doubts....its got plenty of zinc and Phosphorous
They even have a tech line...
You may want to try the 110 Micron Moly
I have been using the 705 Supreme 20W-50 with E-85 and never had a issue but I will probably switch the the 110 because it was designed for alcohol-based fuels.
Here are the specs for the 705 and the Micron Moly
I don't promote things that I don't use myself...I am not affiliated to the company.

API SM
Supreme 7000 Synthetic Plus™ Racing Oil SAE 20W-50 is a premium quality high zinc, multi-grade
para-synthetic engine oil that is specially formulated to reduce friction and wear, increase engine
efficiency and extend engine life in all types of gasoline engines including those that contain flat
tappet cams and those that are turbocharged or supercharged.
Supreme 7000 Synthetic Plus™ Racing Oil SAE 20W-50 is blended from the finest quality severely
hydrotreated polyalphaolefin (PAO) synthetic base fluids and severely raffinate hydroconverted
Group II Plus available. This unique combination provides Supreme 7000 Synthetic Plus™ Racing
Oil SAE 20W-50 with the following advantages:
1. Superior Cold Weather Startability and Operating Characteristics - This results in less
friction and lubricant drag in the engine and instant lubrication during cold weather start up
2. Superior Oxidative Stability
3. Excellent Resistance to Thermal Degradation
4. Excellent Low Volatility Characteristics - This results in reduced oil consumption and
increased protection against the formation of deposits
5. Lower Pour Point and Borderline Pumping Temperature
6. A High Viscosity Index - This results in minimum change in viscosity. The adequate viscosity
for the proper lubrication of the engine is provided regardless of temperature.
7. Excellent Film Strength - This results in increased protection against wear.
8. Compatibility with All Types of Seals
9. Extended Oil Drain Capability and Intervals
Blended into the para-synthetic base stocks is a highly advanced proprietary performance racing
formula additive package and a highly shear stable viscosity index improver. This combination
provides the Supreme 7000 Synthetic Plus Racing™ Oil SAE 20W-50 with the following
performance benefits:
1. Extra zinc anti-wear additives to protect flat-tappet cams from excessive wear
2. A novel zinc anti-wear additive system that minimizes volatility and chemical
breakdown of the zinc anti-wear additive in order to provide maximum and long lasting
anti-wear performance and robustness needed to protect the engine
3. Outstanding protection against the formation of high temperature deposits
4. High detergency and dispercency to suppress the formation of deposits, sludge and
varnish
5. Active cleaning agents for increased and enhanced engine cleanliness
6. Exceptional protection against the formation of coking deposits on turbochargers
7. Exceptional protection against thermal breakdown during high engine oil operating
temperature conditions
8. Rapid circulation and excellent pumpability
9. Excellent low temperature flow characteristics and pumpability to provide rapid
circulation and minimize wear during start-up

10. Excellent resistance to thinning at high temperatures
11. Excellent shear stability to resist viscosity shear down and breakdown
12. Excellent high temperature/high shear performance to provide excellent oil film
thickness and engine protection at high operating temperatures and shear rates, while
minimizing lubricant frictional resistance
13. Enhanced lubrication to maintain maximum horsepower and acceleration
14. Substantially reduced oil consumption
15. Extra protection for hot running engines
16. Extra protection for cold running engines in stop-and-go service
17. Reduced oil ageing allowing for increased drain intervals
18. A substantial reduction in ring and cylinder wear
19. Reduced bearing wear and increased bearing life
20. Excellent rust and bearing corrosion protection
21. Increased engine cleanliness
22. Superior valve train-wear protection
23. Increased engine life
24. Excellent anti-foaming properties
Further blended into these synthetic blend base fluids, the highly advanced proprietary performance
additive package and shear stability viscosity index improver are two proven frictional modifiers,
Micron Moly®, a liquid soluble type of Moly and Schaeffer Mfg’s own proprietary additive Penetro .
These two proven frictional modifiers once plated, form a long lasting slippery tenacious lubricant
film, which prevents the metal surfaces from coming into contact with each other. By preventing
metal-to-metal contact, damaging frictional wear is prevented from occurring. This prevention of
metal-to-metal contact and reduction in wear results in:
* Increased fuel economy
* A low coefficient of friction
* Significantly less bearing, ring, piston, cylinder, and valve-train wear
* Increased engine efficiency, durability and life
* Less down-time which reduces maintenance costs
Supreme 7000 Synthetic Plus™ Racing Oil SAE 20W-50 can be used in most types of 4-cycle aircooled or water-cooled motorcycle and ATV engines including those motorcycles that have a
common sump for the engine and transmission (non-metallic clutches only).
Supreme 7000 Synthetic Plus™ Racing Oil SAE 20W-50 is not recommended for use in those
motorcycle and ATV applications that specify engine oil that meets JASO MA or MB. Use of
Supreme 7000 Synthetic Plus™ Racing Oil SAE 20W-50 in applications that specify JASO
MA or MB oil can cause slippage and improper engagement of the clutch mechanisms.
Supreme 7000 Synthetic Plus™ Racing Oil SAE 20W-50 is also not recommended for use in
4-cycle marine engines that specify the use of a NMMA FC or FC-W four cycle engine oil.
Supreme 7000 Synthetic Plus™ Racing Oil SAE 20W-50 meets and exceeds the following
specifications and manufacturers’ requirements: MIL-PRE- 46152E, CID A-A-52039B, API Service
Classification SM, Ford ,General Motors, Chrysler; specifications and JASO JIS K2215
