0W-30 is good oil: "Mobil 1 0W-30 is the most advanced performance synthetic engine oil designed to provide the cleaning power, wear protection and enhanced fuel economy performance." Another oil site says: "All three oils (0W-30, 5W-30 or 10W-30) are excellent motor oils and ANY one can be used in a vehicle which requires either a 0W-30, 5W-30 or 10W-30 oil as well as in several other engine applications including an engine which recommends a 5W- 20 oil. This leads to the next topic: many people also ask us if the 0W-30 is too thin a viscosity oil for high ambient temperature operation. The answer is absolutely not! Thicker viscosity oils are not always necessarily better since in addition to its' various engine lubrication functions, an oil must also effectively transfer heat. Only about 60% of an engines cooling is performed by the engine coolant, and only on the upper half of the engine. The remaining 40% of an engines cooling is performed mainly by the engine oil." Yet another site: "0W-30 flows up to seven times faster than conventional oils. Therefore, it provides superior protection for engine parts during cold start-ups. And it safeguards your engine when it's extremely hot. Plus, 0W-30 helps maintain low oil consumption and reduces wear on starters and batteries." I can find more examples, but trust me on this: I have used 0W-30 in my last five vehicles since 1997, and it does a fine job. It doesn't evaporate, and it helps fuel economy by reducing friction. |

Any comments on the 2005 owner manual stating the mechanic should change the trans fluid then run the car,then drain and repeat process three times. I doubt a dealer would really do this. Thanks for the input on the oil change.

Mobil 1 Racing 0W-30 SAE Grade 0W-30 Viscosity, ASTM D 445 cSt  40ºC 56 cSt 100ºC 10.3 Viscosity Index, ASTM D 2270 175 Sulfated Ash, wt%, ASTM D 874 1.2 HTHS Viscosity, mPa·s 150ºC ASTM D 4683 2.99 Pour Point, ºC, ASTM D 97 -54 Flash Point, ºC, ASTM D 92 234 Density 15º C kg/l, ASTM D 4052 0.851 Mobil 1 0W-20 SAE Grade 0W-20 Viscosity, ASTM D 445 cSt 40º C 43 cSt 100º C 8.4 Viscosity Index, ASTM D 2270 165 Sulfated Ash, wt%, ASTM D 874 1.28 HTHS Viscosity, mPa·s 150º C ASTM D 4683 2.61 Pour Point, ºC, ASTM D 97 -57 Flash Point, ºC, ASTM D 92 232 Density 15º C kg/l, ASTM D 4052 0.855 The differences are almost negligible, but I still use 0W-20. Exxon does not list viscosity at 0C, but if you look at difference in viscosity for 0W-30 and 0W-20 from 40C to 100C. I can imagine that 0W-30 is more viscous at sub freezing conditions. You can see that by the lower pouring point of 0W-20 vs. 0W-30. But, all in all, any synth is better than dyno oil. |

Replying to: budd (May 12, 2004 1:30 pm) The 7th gen Civic's fuel tank is shaped such that it is highly variable as to when you have actually filled the tank. I know this because on occasion I've put more gas in my Civic than the 13.2 Gal capacity and driven for 50 more miles before the guage moves off "F". Sometimes I know the tank isn't quite full despite the pump's auto shut off kicking in. You shouldn't manually fill the tank once the pump shuts off to avoid draining into the emissions system. Why is this importatnt to know? Because when you only drive 100 miles and then refill, your mpg could be way off depending on when the pump shuts off. Solution: Use at least 10 tankfuls of gas returning to the exact same pump every time. Calculate your mpg each time and average all 10 readings to arrive at a reasonably accurate number. It's possible to fill-up, drive 50 miles, fill-up again and the pump shuts off after only half a gallon added (pump shut-off calibrations differ at different pumps) and calculate your mpg to be 100. Of couse 100 mpg is impossible. |

Replying to: mauto (Sep 28, 2004 4:50 pm) I've owned 12 cars in the last 25 years, and I have only once ever put more fuel than the tank was rated for, and that was only 0.1 more.....

Replying to: larsb (Sep 29, 2004 6:17 am) ___I have owned 12 vehicles in the last 10 years and all have been able to be filled beyond specified capacity. Currently, the Corolla will hold > 15, the Insight > 14, and the MDX > 22. ___Good Luck ___Wayne R. Gerdes

Replying to: xcel (Sep 29, 2004 4:11 pm)  I know for sure that the following cars did not hold more than their rated tank capacities, because in these cars I *HAVE* topped them off and tried to shove every ounce of gas I could in them before learning the evils of topping: 2001 Avalanche 2000 Tacoma 1997 Suburban 1998 CR-V 1996 Camry 1994 Maxima 1993 Q45 1992 Cressida 1990 Cressida 1987 Maxima 1984 Maxima My 12th car is the 2004 HCH, which I have not been able to put more than 12.5 in so far.

Replying to: larsb (Sep 30, 2004 6:24 am) Wayne, so you are TOPPING OFF your tanks? You know that is a naughty thing to do.... ___Yes, I top off all my tanks and have been doing so for over 25 years. I have never been scolded for doing anything naughty in regards to fuel fillups however  With that, I have probably saved a few hundred gallons of fuel over the last 800,000 miles by not having to drive to the gas station and back nearly as often. ___Your evils are mistaken … ___I cannot speak of the entire list of automobiles you posted but your HCH is either a ULEV or PZEV. If it is a ULEV, you most certainly can fill it up with more then 12.5 gallons. What you are probably not taking into account is that you never drive any of them to low enough fuel to place the rated capacity of the tank in them. ___Good Luck ___Wayne R. Gerdes |

Wayne, I stopped topping after doing a little research on the subject - check it out yourself and rid yourself of such an environmentally nasty habit which can also damage your catalytic converter.....even the EPA warns against it.... Yes, my HCH is a SULEV with a 13.2 gallon tank. I have yet to trust the gauge enough to drive it emptier....I will over time do so, however. |
