Tim is posting up regarding oil consumption in his engine, without sounding arsey, of course people are going to discuss oils
honda reccomend 5w30, so instantly he is using a different oil than that reccomended, as do most people
As for saying that using a basic oil will have prolonged affect on engine life, this is rubbish, most oil related issues are due to inadequate care to the engine (not allowing the engine to properly heat up for example) and service intervals (dirty oil, letting the engine run low on oil etc etc)
I'm not saying there isn't advantages to running fancy expensive fully synta oils, however you shouldn't believe everything you read
I used to run castrol GTX, but been hard to get local so now run mobil 1 pro 2000 (both 10w40 semi synta), have done for the last 28k miles. I also run a spoon ecu and rev it higher than the oem rev limit frequently on standard valvetrain, had this for about 15k miles now. engine is strong, burns almost zero oil. I don't for one see my engine as a ticking time bomb, am i going to change oil to fully synta because someone says it will be better? no
Sorry for the rant, but annoys me when people believe what they read too much
As bad as it sounds, i would hazzard a guess that it's your bottom end that has issues Tim, with no details of who carried out the work to the engine, for all you know the stroker kit could have been fitted straight into the block with no rebore/hone etc
( Cheap way to check the stem seals would be to whip off the inlet and exhaust manifolds, take a look in the inlet/exhaust ports for oily residue
