myself I would use HPR30 penrite how ever I know plenty that use lighter oilsVGJONO wrote:Just wondering what oil you guys would use in a 4G32 that has only done 20,000klms since rebuild, the engine is mostly daily driven with some spirited drives on mountains and what not every now and then and track days every now and then. just wondering as it seems my choice of 15w50 wasnt a good one, but the recommended 20w-50 just sounds too thick to me for an engine that hasnt seen much work.

a few weeks ago i went for a drive to the sunshine coast which meant highway driving, started off doing 100kph @3200rpm and 60psi of oil pressure, about 45 minutes into the trip @3200rpm i had 40psi, i took it easy and stopped a few times when i noticed the pressure dropping and once letting it cool off i would get on the highway and it would be back upto 60psi, i had a talk with some people and they suggested it was the wrong viscosity oil.davetrees wrote:What's wrong with 15W50 ?
my astron would get an oil and filter change before every event it didn't matter if that was a hillclimb - sprint or state race rounddavetrees wrote:There's not that much difference in price between known, good quality oil & "cheap stuff" ... so I use the good stuff & change it regularly (every 2 or 3 events). Cheap insurance I reckon. The day I can't afford to spend $40-odd on oil a couple of times a year, it's time to stop rallying .....
..... and while I agree that my engine isn't necessarily "high performance", it does spend most of it's time pulling lots more revs than your average road car would so I figure it can use all the quality lubrication it can get !
