mobil 1 oil

hootymo · #1 03-25-2005, 03:21 PM

hi guys, just wondering if it is still a good idea and if i would benefit from putting mobil 1 into my 2000 lt with 96k miles. i heard that after a while the engine gets pretty gunked up from the crude oil so putting synthetic in an already gunke dup engine doesnt do much, do you think this is the case with my 96k 4.3?? i pull the dipstick out sometimes to look at the oil and it looks very very clean, im impressed with it. i was just going to run a can of engine flush in it and change over to synth, btu if you guys dont think its worth it then i wont. i figured i would consult the pros first :-) thanks

It is well worth it.

mobil is a great oil and i have ran it for a few years and love it.
I would not do a engine flush though may do more harm than good.
You can do quick oil changes but mobil is pricey for that.May want to use a cheaper oil for that purpose. Chemical engine flushes I would not.

I would go with the flush. If you don't get the junk out it will just mix with the mobil1 and limit it's effectiveness.

Before my blazer, I had an 89 Z24 cavalier with a 2.8 liter. This had a 5 speed manual, and I used to just beat the heck out of it.

Anyway, at around 90,000 miles I switched to the Mobil 1 (no flush, just a regular oil and filter change) and when I sold the car last year, I had just turned 218,000 miles.

Car is still going strong for the new owner, doesn't leak oil, doesn't burn oil. I use it in the Blazer and my wife's minivan; spend the extra bucks for the synthetic; it's well worth it down the road.

Just make sure you DON'T use a Fram oil filter.

thanks for the input guys, im still not sure though from what you guys are saying if its a good idea to do a flush or not? any final word? thanks

I would flush - Your mileage isn't that high and it would really help your syn oil to stay clean. Just remember to follow the directions to the letter and let ALL of the crap drip out. I would let it drip for at least a half hour or more then install a good filter. You may want to consider changing it again after 2-3k miles just to be sure all the junk is out.

excellent, thanks!! now any recommendations on a good engine flush? i hear the "GUNK" product is one of the better ones, i have always had good results with it. any other good ones, or is that the best one?

BlazerLT · #11 03-27-2005, 01:52 PM

That is what I use, just idle it for 40-45 minutes in a WARM engine and remember, if you go over idle, you will cause damage.

its a myth that you HAVE to flush between changes, think of blend oil, its mixed synthetic and patrolium... i would just do the switch and then do a change at 1500, then go 5k... as to the new product clame, the oil will hold up for the 5k 7500 and 15k... but let me ask this, can the filter keep up for that long? i dont reccomend more then 5k on a filter, they get "stuff" (yeah i know its extreamly technical) into it and cloggs up and just goes through the blow by, which in turns means the filter isnt filtering anymore

poor advice,

You are asking him to not do a 3 dollar engine flush but instead change out a synthetic oil check after 1500miles?

$3 or $30?

You be the judge,

i dont like the flush products, ive told people how to do them, they dont listen (people i know are idiots i know) and wind up fu*ken up something because they get impatient... if you can be patient and read the directions and do it word for word, go for it, just know, that when they say dont rev the moter, that is exactly what is ment!

BlazerLT · #15 03-27-2005, 11:34 PM

True, I understand that, but using a flush before going to synthetic is not a myth though.

That is what I was trying to make clear.
