Re: oil pressure of new engines
I would caution using penrite after the few lots i've used.
First the XF making terrible lifter niose, replaced the oil with penrite again, problem came back after 1 week, replaced with pennzoil 'street machine' blend... problem fixed! Hasn't come back in 2 months.
The old BB 390 was even worse. The penrite went in 3 days before the dyno tune was ment to happen. The lifter noise was so bad the guys at Hallam wouldn't let the car on the dyno. The first thing they said was 'Your using penrite aren't you?'. Apparently they have heaps of problems with it and despise it. I wanr back to pennzoil street machine, niose was basiaclly gone, but did show up a major ring seal problem at 2000rpm+ so its rebuild time! (stock '65 engine, not a bad effort!).
Just like a Tsunami.
