MAC, he's only had it one year. ;)
Note his mention of tripling it's mileage in one year? Previous owner was the proverbial old lady. Now back on topic...... |
I garuntee at least an average of 3 mpg if you try royal purple. You will argue, but your car will show a noticable differance on smoothness. Right now we have mobil on on sale at napa for 5.19 a quart and royal purple is 5.69 a quart. not a huge differance? if you see it for 7 bucks they are privately owned..... And yes 3.8 engine do last forever but the way i drive and the -35 below weather we have right now, conventional oil has no chance against synthetic. Napa Oil is identical to valvoline oil just waY cheaper. Made in the same plant of Ashland Oil. You may argue but check it out your self. Also check what oil you use in your car and tell me what temp it can protect your engine 100%.. ;)

Which is another suggestion I have for you all. Start carrying a little notebook and record your milage. This may seem like a lot of work, but it helps to keep track of the car's usage. I typically crank the car up in the morning, let it idle up to temp while I fetch a mug of coffee for the trip, then head off to my first call. Writting down the date, odometer, and location when I get there. Oil changes, service items, fuel usage all get jotted down in the little notebook too. Any failures/quirks go in there too. Every so often I compute the gas milage of the longer trips, just to see how the engine is doing in terms of fuel consumption. Side benefit: Come april, when filling out form 1040 Sched C, I can confidently say "Yes" to the question "Do you have a written record? " |

i.e. it's easier for the metal to move through synthetic than its thicker counterpart. Source? The Law of Conservation of Energy. |
Find me a 3800 with an oil breakdown related engine failure. |
I currently am running Mobil 1 with a PF47. This is the first time I am running it to 5,000 miles. I usually change it around 3,000. It is due in about....2,500 miles yet. Its nice not having to change it so much. Oh and satisfaction on Mobil 1? My engine runs WAY smoother, especially at high RPMs, I get better gas mileage, and I know my engine will be protected in the severe cold like we're having right now.

I agree with the Royal Purple scam call above. Find me a 3800 with an oil breakdown related engine failure. That's a challenge. I'll keep my Mobil1 at 5000 mile intervals. |
