I have 3 questions that I would love to get answers for. I have a 2009 Honda Civic LX-S and 2006 Acura TL Questions here relate to both of my cars, but probably More importantly to the 2009 Civic: 1. Does switching to Full Synthetic oil help with the MPG, and if it does, by how much. Did anybody over here gone from the conventional to the Synthetic? what was the jump in MPG they saw? 2. Also, I understant that once I Switch from conventional to Synthetic, then there is no Going Back? (once on Synthetic oil, one has to stay with Synthetic?) 3. once on Synthetic oil, how often do you change your Oil every 7.5k miles/10K miles? not different than with the convetntional? I like to think of Oil in the car as the blood of the car.. need to have it CLEAN! PS. I saw the Mobil1 Full synthetic for a fairly good price at CostCo... but I am not sure if that is the best Synthetic oil out there. Thanks for any help and info! -ChicagoGuy! |

Did anybody over here gone from the conventional to the Synthetic? what was the jump in MPG they saw? Ans: There are a WIDE (and I mean WIDE) range of variables. The answer can be a firm yes to: an ah... maybe/ not. My experience/take is a 1 to 3 mpg range. Is it a guarantee? Absolutely NOT !!! Yes, I had plan to go over th Mobil One 0w20, 5w20 right after the 10,000 miles recommended with factory fill break in oil OCI. (for your particular applications, RTFM for your 09 Civic and 06 TL, but I think it is 0w20.5w20) 2. Also, I understant that once I Switch from conventional to Synthetic, then there is no Going Back? (once on Synthetic oil, one has to stay with Synthetic?) ANS: No, that is not true. Indeed they are compatible with each other. You can mix and match them. My take is once you go to synthetic, why would you want to switch back under normal conditions? 3. once on Synthetic oil, how often do you change your Oil every 7.5k miles/10K miles? not different than with the convetntional? I like to think of Oil in the car as the blood of the car.. need to have it CLEAN! ANS: I change every 20,000 miles. If I had decided to stay with conventional oil, I would change it out  10,000 miles. Your last sentence can be covered more in depth on the thread synthetic oil on Edmunds.com. Again like you oil is the life's blood of the car. CLEAN can be a deceptive description. PS. I saw the Mobil1 Full synthetic for a fairly good price at CostCo... but I am not sure if that is the best Synthetic oil out there. My take is NO. Mobil One is not THE best out there. However it has a lot of really cool attributes: 1. It is a widely available PAO IV product. (Costco, WalMart to name 2) 2. It is competitively priced with so called hydro cracked Group III "synthetic" products 3. It goes on sale periodically 4. Best bang for the buck (for my .02 cents) and I have been using various Mobil One products for over 1.2 M miles.

Replying to: westy1 (Aug 24, 2009 8:39 pm) However for the US gal (128 oz per gal) the mileage is 367.2303 miles/9.246 gals= 39.72 mpg US. All the best and keep at it !! |

Just bought a 09 Civic EX w/auto. Using as a commute car and not experiencing very good gas mileage. Curious about: 1) break in procedures (if any) and 2) is it normal for gas mileage to be lower than optimum for first 3-5K? Many thanks!

Replying to: pmaenter (Aug 26, 2009 5:20 am) What mileage are you getting? |

Replying to: pmaenter (Aug 26, 2009 5:20 am) least 75% of redline and don't even think about mpg optimization. for at least 5,000 to 10,000 miles or that first break in oil change (10,000 miles OCI) .

Replying to: ruking1 (Aug 24, 2009 8:28 am) I think we all got accustomed to the gas being at $4/gal, we condider today's prices cheap. ... where in truth, gas is still expensive! even if it drops another 30cents once summer is over. I am also itching to change the oli every 10K miles, but got to read up on what the folks are saying here... maybe "changing every 15K" would be sufficinet. Also the dealer reccomends the first oil change at 7500 miles. And i totally agree Mobil1 Full Synthetic may NOT be the best synthetic out there, but it is the best bang for the buck! Thanks again for sheading the light! Truly appreciate it! -Chicago1985Guy
