Motor Oil ??

[Jersey General]

On a recent road trip, the low engine oil light came on just as I arrived at my destination. I added a quart of valvoline max life full synthetic, 5W30. Does anyone have any experience with the max life product line. I typically use the regular full synthetic. Any thoughts on the grade of oil? The max life was an SL grade. Will SL meet SG/SH standards?

Thanks

No experience with the max life product but I believe the standard goes up as that second letter ventures further into the alphabet. Therefore the SL standard exceeds the SG/SH.

the valvoline maxlife has between 10 and 20 percent of its content made up of full synthetic oil. its certainly not the worst thing you could possibly put in there if you are topping up with non synthetic. my engine likes it very much (no more use than mobil 1) , and the 10w40 gets me the same gas mileage as their 5w30. i'd use it again if i could get another "free" 5 quarts of maxlife after rebate.

not in an M50. 10W30 until your VANOS unit starts making noise (usually higher mileage) then 15w50 once you hear the tapping from it. I personally use Mobil1 and Amsoil.

this weekend, i'll be installing the german castrol 0w30 oil into my m50 (aka jesus among synthetics under $6USD) and see how she fares. the car will be used as a delivery vehicle starting next week, so we'll see how long it holds up under severe start/stop cycles before it breaks down according to the Roopnarine method for viscosity determination :D . multiple tests at bobistheoilguy put new GC 0w30 at a viscosity of 12.2 at 100C, which is just on the borderline for a 30/40 weight (40 starts at 13). m1 0w40 tests between 13.2 and 13.5, so i doubt there's going to be that much difference, especially since both are very good oils. i know that i could certainly stand to stomach a few extra mpg now, so i wont sweat the fact that its a 30 wt. (i'm sure i'm not the only m50 owner in a warm climate running a 30wt).

I was going to change my oil for the first time this weekend and I was going to use regular 10W30. But now as I've been browsing these forums and searching around it appears that I should synthetic. Am I correct in stating that once you use synthetic in an engine that you should never go back to regular?
I'm located in Western PA and we get some cold winter spells. So that being said should I stick with 10W30 in the winter time too?

thats complete nonsence about switching one way or another. Get some mobil one 0w-40 and use it all year around, change it every 5000-7500 miles.

boo! u are teh suck! i was actually gonna ask if i could use SAE 40 wt in it if it was going to be used for delivery, but then i realised that the only benefit i'd see in that situation is if it were a taxi cab or police car. this car will be started/stopped too much for that. the bentley AND bmw certainly says i can use that thickness in the climate i live in...... i wanna see what kind of benefit green motor oil will provide me with. ;)
