I've just rebuilt my h22 last year and have been running regular 10w-30 oil for about 15-20,000 kms about 10,000 miles... Before the rebuild I changed the car over to synthetic and it was burning quite a bit of oil... The motor seems to hold oil very good after the rebuild.. Should I change it to synthetic or just keep using regular oil and change it more frequently? Kinda worried about messing up an engine that runs great as is.....thx

 

My opinion would to be stick with regular oil. Just my two cents though.

 

As you know, my engine is being rebuilt now, should have it back next week, and I plan on running regular for 500 miles, then another change for 1500 miles, and then in goes the synthetic. AmsOil Series 2000 0W30 racing oil.

 

If it aint broke, Dont fix it!

 

my experience: rebuilt motor - car went about 20000 miles on 5w30, then I bought it, switched over to synthetic and I have had almost zero leakage between oil changes.

 

thats good to hear.... I'm thinking of changing cuz I do go to the strip a couple times every month and I run it to 8000rpm all the time.. This being said I change my oil very frequently....

 

for someone who doesnt know (like me), why is it bad to change over to synthetic from regular?

 

Tend to burn more synthetic but I'm staying w/ it better lube action IMO

 

i have heard also if you run synthetic sometimes that it will make the rings soft and dont allow them to seat well, i have been wanting to change mine over but i have been worried about this

 

im just a beginner with this engine ****, but i had a problem with synthetic https://honda-tech.com/zerothread?id=516742
and i agree with the other fella, if it aint broke dont fix it, sorry about the grammar im from new zealand
