10w30?

[stapletonb08]

I put 10 w 30 in my 2.2. Will this effect anything like gass mileage or power?

That's what I always use. Been that way for about 5 years now with no problems.

It won't hurt anything, I run 10w30 in the summer and 5w30 in the winter, no problems.

FYI, you CAN'T do it in a V10 Ford. The oil galleries are too small.

Ok. I thought it would be fine. Has anyone tried Bosch platinum +2. I just put them in today. I havnt noticed any change.

Gimick!!! It's just something else to brainwash you into believing that they are better or will give you more spark, more power, better gas mileage, etc etc etc. to me the plat.2's and 4's divides the spark
Feedback from past customers most prefer NGK, AC Delco, and some are testing the waters with the E3'S in 2.2's

All the higher viscosity-point number will do is give the engine a li'l firmer cushion of oil to have between it's clearances when the atmospheric temperature is about so-low or ensure the cushion maintains a nice, thick firmness when the engine's operating temperature is so-high. If the temps start going beyond the operational range in which the oil can maintain it's "thickness", that's time to worry.

10w-30 is very commonplace in usage, since it does well in maintaining it's viscosity while seeing the temps normally seen in average, normal driving situations day-to-day year-round in cold-weather-month states. Only when the mercury dips real low or skyrocket's does it possibly become a problem. Otherwise, anything that calls for 5w-30 that'll see only normal, pedestrian driving everyday is just getting a recommendation for it to be used so as to eek-out a li'l more mileage form the engine in question, in hopes to coming as close to possible to whatever the CAFE-rating test-result was while being driven in a real-world fashion. Yes, it used what's recommended while testing... But still..!

I use 10w-40 in the summer & 5w-30 in the winter just to play it safe, and look at what I get: 23.5avg-mpg.

Oh, one more thing in relation to your other thread: For some reason I can only speculate on, the pre-'98 LN2s get better mileage than the post-'97s... And that includes the OBD-I years with the "lesser" management (Non-sequential injection, injections triggered supposedly as the valve is starting to close (Different DIS crank-trigger clocking)). My best guess is that GM was wise to how exactly the testing of the vehicles for mileage went, and they re-engineered the LN2 to maximize what it's get in those tests so they could still meet the mandate & not worry so-much about what their "heavy-drinkers" got. But again: As-tested versus actual real-world... God knows it gets me how my '94 does so-well & the best I can average from the '99 is low-18s. And both trucks are built exactly the same!!
