1998 Toyota Sienna and M1 Truck & SUV

[Andrewsreef]

Hi, I have been using M1 10W-30 in my wife's van for about 40k. Would Truck and SUV be a good choice for the van also? I have used T&S in my other veichle and really like it. Seems to quite the motor a bit at idle (may just be me).

Will the T&S hurt the gas mileage?

Thanks

Andrew

It may hurt gas mileage, but it's probably the single best oil to use in that engine that you can by over the counter.

Don't forget to change that PCV often!

Now that Pscholte has had that talk with me, allow me rephrase what wrote...ahem..."It may hurt gas mileage, but it's probably one of the two best oils to use in that engine that you can buy over the counter, GC being the other."

(I can't believe I misspelled "buy" in my first post)

I posted these results in another post. One factor that could be skewing the results is A/C usage during the 5w40 run, the A/C was not used as much for the 10w30 ???? Oklahoma gets hot !

The following mpg numbers are for a 1995 Ford Taurus 3.0 using 10w30 Mobile 1.

1/9/2005 82,134 173 9.8 17.6

MPG numbers for Mobile 1 T&SUV 5w40

6/28/2005 86,174 150 7.7 19.6

7/30/2005 86,869 245 12.8 19.1
8/3/2005 87,062 193 10.5 18.5
8/9/2005 87,300 238 12.0 19.8
AVG 19.1

Not a controlled experiment and not enough data to make a firm conclusion, but I saw about .2 mpg decrease. I sold the car to relatives in FL so the experiment is over

BTW According to the new owners the car averaged between 28 and 29 mpg on the trip to FL.

Hi,
aircon use does have a truely negative affect on fuel economy

Amongst Porsche 928S4 owners (with real time computer) the "usual" variance on averages are;
Aircon off - 11.2ltr/100km (25.2 mpIg)
Aircon on - 12.2ltr/100km (23.1 mpIg)

For what it's worth

Doug

First of all, TnS, good on ya! Now to the mood of the moment...My current thinking is that, given the the timing of its appearance, its interesting chemistry, its demonstrated performance, and the resulting mystique that surrounded The Elixer of Life, Love, and Lavish Lubricity--Das Grüne Öl--we may not see its likes again for awhile. I am not saying we won't see oils that perform well or that are "interesting," but all factors considered, I think The Green was a phenomenon not oft repeated...and for that I am genuinely sad

. For those of us that still have ample stores of The Green, it is a time to cherish. To make sure no one misunderstands, have I abandoned the Gold--no way--but if production does indeed begin (or has begun) in the US, it won't be the same (no slam on US produced product, it just won't be the same).
