Two modified late model Mustangs. These cars run open track events,
solo II and hard street driving. Engine modifications include 80mm
MAFs, large throttle bodies, GT40 upper and lower intakes, ported
factory heads, B303 cam and full length headers. The cars weigh about
the same and the drivers use the same shift points (6,000 RPM). They
both run the same Earl's oil cooler with the same type of
installation. The cars always run at the same events.
If you run a late model Mustang, you'll have to run pretty hard to
beat up your oil more than these guys do. Their cars make power well
above 5,200 and they spend a fair amount of time there.
History
The cars both received an oil change at the beginning of the season.
Ken ran the new formula Mobil 1 in 10W30. Rob ran Redline 5W30. Open
track events included two hot days at Waterford road course and 2 hot
days at Gratten road course. They also ran two Solo II's and hard
street driving. Total mileage for the season was 6,000 miles (on both
cars). The cars were garaged in the fall and the oil samples were
collected near the end of Winter.
Results
Redline did not outperform Mobil 1. Both of the oils performed just
_fine_ for 6,000 miles of street and track abuse. Unfortunately, for
test purposes, neither oil significantly gave up the ghost. Both oils
were in excellent shape when tested. The actual numbers for Mobil 1
at first glance look much better than those for Redline. However, it
must be emphasized that both of the samples are in excellent
condition. The numbers are so low (which is good) that if another
sample was taken the results could be reversed - the numbers for
Redline could be better.
Note that the results for the Redline oil showed a higher amount of
Silicon, and that makes sense, according to the engineer we consulted.
Rob had recently replaced his intake. The higher Silicon content in
his oil is the result of the Silicone based RTV used to seal the
manifold. Pretty neat, eh?
Note that the viscosity for the Redline is slightly better. Higher
reving engines will tend to reduce the viscosity more. Since we
didn't really damage either of these lubes (too bad
I really
wonder how the results would have been after a 24 hour endurance race.
