I have been reading at great lengths though the previous formus, cant seem to fine one specific sticky that really pinpointed what I am looking for (if there is I appologize in advance). I live in Vegas, its the season of HOT, getting ready to break triple digit heat here sooner or later but I am do for my next oil change (yes sorry one of those :|). I was reading in the manual for the oil 10-30, 5-20, or 5-30. My last oil change I belive the 5-20 was used. Im not sure it was me but the car drove diffrent, seemed not as smooth or well I cant call a 4 cyl engine powerful but seems to be lacking some oomph if that makes sense. Think its normal conditions about 12miles each way to work, only go about 5-10 over depending on flow of traffic but there is this hill I have to drive up home that seems to require my foot through the floor to maintain speed (if anyones from the area its the 95 and Horizon).
Id like to go the synthetic route but was looking for your opinions and see what the more professional or knowledgable people know, or is there anything that can help here? Thanks in advance.
If you're requiring WOT just to maintain a speed below, say 105 MPH while going up a hill then there's something beyond just oil causing your problems. 5W20 is what the car specs for from the factory and it should run just fine on that. I switched to 10W30 to reduce the notorious valve clatter at startup and still have no issues accelerating up a two-mile long 8% grade coming out of the Vista Ridge Tunnels on US-26 and maintaining 65-70 MPH.
How many miles on the car? Auto transmission? What year/model? I use synthetic and like it better. Who does your oil changes? Have you ever done an engine flush product like Gunk or Seafoam?
I just buy the cheap WalMart brand full Synthetic 5-20 oil and OEM filters. Works great. Usually after winter I run a flush product for a few minutes and then drain (extra long time)
sorry I got the 2011 elantra, 1.8 engine I believe. Auto transmission. Original stock Optimo tires (wonder if thats part of it I hate these tires)
Whats WOT? No, tring to maintain between 65-80 depending on traffic, flat surfaces fine just hills are a drag, but I know the 4 cyl isnt exactly built for speed or power. No never flushed engine, I bought it used its only got 29,500 ish. ECO not on, cause its one you have to do through the wheel controls and not on that side panel where the dash light dimmer is.
Yes and any name brand synthetic is good Mobil, Pennzoil, Valvoline etc.. I buy whatever is on sale, usually can find a Pennzoil mail in rebate at oil change time.
Just a thought but one time we had a car lose power after a garage did an oil change and I found a vacuum hose was knocked loose. May not be that but check around and make sure you or a mechanic didn't hit a plug wire or something else. May be that simple.
Ill check didnt see anything, i went with the 5-30regular, unfortunatly due to some finincial constraints synthetic will have to wait til next time. Does run better and, less throttle up the hill, still running about 3000 rpms to keep constant 70 up the hill as to not get run over by traffic. Seems to be combo of a bit overdue on oil change and wrong air pressure in my tires (had a screw in one so that didnt help) but next payday will be a rotate and balance as im also overdue for those, but thank you all in advance.
