Hello to all I recently bought a 2008 Civic sedan 5 speed Love the Car
want to keep it as Long as possible so im using 5w20 Pennzoil Platinum
in winter months. and a synthetic Puralot oil filter and adding a can of BG MOA oil additive

im just not quite sure if 7,000kms or 8,000kms is ok to change the oil out?
I live in Canada,ont

 

Yep full synthetic is supposed to be good beyond 6000 miles or around 10,000 km. My bmw recommends every 15,000 miles or damn near 25,000 km

 

synthetic oil does last longer but i wouldn't go buy the oils recommendation i would go buy the oil filters recommendation. if the oil last 15,000 miles but the oil filter is only good for 9,000 miles your not going to run it 15,000 miles.

 

Im going by the owners manual recommendation

 

if your using synthetic but going by the manuals oil change intervals then your just wasting money buying synthetic.

 

Ive been avoiding arguing with you for three days but I cant resist. Sorry.

1st of all I was talking about my bmw. 2nd of all i havent wasted any money because I havent reached 15000 miles to change the factory oil.

 

1st of all op is talking about an 08 civic not a bmw i didn't want any confusion on your behalf when stating "Im going by the owners manual recommendation" how do we know what car your referring to ?

 

Yes theres no way to figure out what im talking about by reading what i typed.

Also please forgive me for thread jacking this guy by doing a comparison of synthetic oil lifespans. Im sure hes going straight to bmw to get their x1 owners manual so he can maintain his car as if it were a bmw too. Sorry for the confusion

 

Generally speaking, that km/yr range is just fine for synthetic oil change intervals. In severe winter driving conditions, you might want to stay on the lower end of that, in summer driving conditions, maybe longer yet. What does Honda recommend for a 2008? My 2013 is 0W20. I imagine your manual also gives you oil change interval recommendations for normal and severe driving conditions. As for BG MOA, I rarely see manufacturers recommend using aftermarket oil additives. Might be a good idea to search for online studies of the product in impartial testing. IMHO, if you change your oil when you should, additional oil additives aren't necessary.

Blackstone Labs will do inexpensive testing of your used oil if you want to see some in depth analysis of yours. I've used them in the past and they provide some good info and recommendations.
