its never given me any problems but when does oil give you problems lol well ya i like it beacuse when you touch it with your fingertips it feels really thick so it feels good that little to no friction will happen in my engine. i use it in all my cars so im pretty happy with it hows the royal purp 00civic?

 

i use royal purple as of now. first time using it! i find it awesome. lifter noise i had is gone. it may be in my head but the power seems to be there and my motor is running cooler, but the oils before was a non synthetic cheap brand so anything was an upgrade

 

Royal Purple FTW!!! Have it in my tranny too. LOL ((Yes I know I have some Honda Manual Tranny fluid on the way for the next change))

 

lol yeah i like it man, but you're right i don't think it's too easy to tell ahuge difference between oils unless it's something really cheap

 

Right now i run vavoline but next i am going to spend the extra money and start running royal purple for all the good things i hear about it. Cause its also fully synthethic and just better for your motor.

 

what would be the best oil for an 89 civic hb i been use penzzoil 5w30 146k miles ???
i havent been using it for long i just assumed the previous owner used it an i didnt wanna mess with it. but does it matter if i was to change to synthetic now?? or would it mess up anything?

 

Even though the recommended grade of oil is 5W- 20 (I think that was it) what is everyones thoughts on running 10W-30? Anyone notice a difference?

 

i run royal purple 10w30

 

I tend to think that changing it frequently is better than the oil that goes in. All oil comes from the same source and unless you're doing the kind of driving that requires preventative measures against thermal breakdown and things of that sort, oil properties won't change that much. I'm no expert but from what I've read it's not a HUGE factor. The thing that kills your engine is the acidic residue from soot and other contaminants from combustion. Filtration is very important. So I get anything that's cheap... but it's usually a brand name.
