Oil Change to Brad Penn - Less Leak, more Burn
Recently I changed from Redline 20/50 to Brad Penn.
After 6 months running Brad Penn I've noticed
I leak less but burn more. Anyone else with this observation?

Switched to Brad Penn in spring. Yes, have notice more burn. Adding half a quart every 1,000 miles. With old syn, much less. During check last Dec., valve guides were in great shape.

The '91 I just bought has been running Brad Penn 20w 50 for quite a while (previous owner was a fan). It does burn some, but I haven't noticed any leaks (knock on wood).

Just out of curiosity, why would you use something the manufacture doesn't specify as correct for the car, or have I missed something glaringly obvious?

The old oil specs had enough additives that they lubricated guides and "conditioned" gaskets.
I wouldn't expect a TB issued today for a 20 year old car, because the new oil "works", it's just that some of us have good luck using an oil for which the car was initially designed.
