Holy cow! Did you accidentally use sand instead of oil?! Man... I've NEVER heard of an EG33 wearing out that soon.
I hope you get it fixed. Personally, I'd just try 10W30 first. If that doesn't work, I'd try "RESTORE". I used that once and recieved the best mpg ever with it... maybe it's just a little ring blow by. Use thicker oil, and use that RESTORE stuff.
