hi i just bought an 05 the tranny is slipping but the warranty has that covered however i am a sandwich delivery driver for jimmy johns and right now im averaging 17mpg im getting the trans fixed next month then right afterwards im getting a k&n cold air intake installed and a flowmaster exhaust with an increase from 2 to 2 1/2 pipes for $550 for both my question is what kind of oils and plugs you others use and what the results are im thinking of using bosch platinums and for years ive used castrol gtx high mileage mixed with lucas motor oil with amazing results on higher mileage vehicles however this one is a low mile car any ideas or suggestions i also used lucas fuel injector cleaner in previous vehicles and only shell regular 87 octane gas
As has already been stated, AC Delco plugs are the only ones to use, unless you have mods that demand otherwise (but this WILL NOT be the case for you, so AC Delco plugs are the ones you want.
As far as wires go, AC Delco is the best option. Some of us run PRJ wires as they are also proven, but they cost way more. The benefit is that for those of us that frequently have the wires off the car it's a lot easier to take them off with almost no risk of damage to the boot.
As fas as the oil goes, you should probably stick with what you know. I've been using Castrol GTX high mileage oil in both of my cars for quite a long time and don't have anything bad to say about it other than I need to start buying it in the larger jugs.
Protip: If you don't know what you're doing, don't do it.
thank you for the feedback however on further research im finding that the oem calls for iridium plugs so im going to check what acdelco offers in iridium and you also say that the more expensive wires have little to no benefit except to constant removal and installation?
walmart seems to be the cheapest place to get the castrol gtx highmileage in the large jugs as well as the lucas and sometimes you may get lucky if they have the shelf price mismarked they have to givce it to you for the lower price i was fortunate enough to get a jug once for $3.99 that way and on a side note what do you guys run for oil filters?
