Replying to: ruking1 (Dec 28, 2007 1:12 pm) 1. How do I check the leaks that are plug by the conventional oil? The only thing I do is to check the oil level. The level doesn't change at all since last time I changed the oil 3000 mi ago. 2. I check my engine just by opening the the oil cap and peeking into it. Is it enough? You mentioned to check if there is sludge inside th engine, how does this relate to switching to synthetic oil? (if there is sludge I can switch or if there is no sludge I can switch) 3. The OCI I do with conventional oil is 3000 mi, because most of my driving is cold start in the morning and drive less than 2 mi, cold start again in the afternoon and drive from campus back to my apartment. If I switch to Mobil 1 what OCI do you suggest under the same condition?

In fact, were I in your shoes, I'd definitely opt for something like Havoline 5W-30 and stay with the 3,000 mile OCI. Keep in mind; I am a dyed in the wool advocate of synthetic oil, so for me to recommend that you stay with conventional is very much against my nature. That said, I think in your case conventional oil is the better bet. Best Regards, Shipo

Replying to: dchen2003 (Dec 28, 2007 2:09 pm) So for example, I would have no issues so called "extending" even conventional oil. Indeed I ran the first full 10,000 miles OCI (as recommended by the OEM) on the Honda Civic, again 5w20 CONVENTIONAL oil. If all you wanted to do was to run YOUR full recommended OCI, then run the recommended conventional oil. So in that sense I would be in full agreement with Shipo. No real sense in "wasting" money, time, and resources.

| i noticed they changed it for the 2008 model year...last year it was 5,000 miles...honda is 10, 000...for normal driving conditions....i would imagine synthetic would be 10,000....2 major auto companies say 3000 miles ocis are obsolete...just as long as oil it has that API symbol on it...of course everybody should check their oil and add when needed...in europe they go even longer i think...i think 7,000 is reasonable | |
