what is he complaining about? 5 qts of mobile 1 synth is 20 bucks at walmart. I just changed the oil on my truck and it takes 15 quarts, cost almost 100$ for an oil change. $25 is nothing, and u can get away wiht going 7K with synth oil

 

well you guys are saying that synthetic doesnt fully break in new rings. should i go one period with regular oil, then switch back to synthetic to fully break them in?

 

I went more than that. Last oil change I went 10K. When I changed it, the oil wasn't even dirty. This time I might go a little bit more...

 

I don't think it matters, but do I know. I have never use synthetic oil and I have 265,000 miles on the clock.

 

my original civic cx hatchback has 400,000 miles on the original engine and tranny and it's never had synthetic either.

but if I had a choice, i'd use synthetic in any higher performance car that I buy. It just has better friction/viscosity properties and bakes at a higher temperature.

 

Do you change the filter inbetween?

 

so should i go one time with regular oil to break in the rings or not?

 

moot question. you've already put in regular oil...

 

i still have synthetic in right now.. and ive used synthetic since before the rings were changed, so they've been run with synthetic only. should i use regular to seat them correctly? currently i have in 20W-50

 

i'll just stick with synthetic, screw it, thanks guys
