Official Oil change discussion

Re: Official Oil change discussion

What I've always learned is that if you switch to synthetic, use seafoam, or some other auto cleaning chemical (fuel system cleaner, ect), and it "causes" a leak, chances are the leak was there and it was a bunch of gunk that was plugging it. It's why i go full-on synthetic--I'd rather catch a leak early and fix it properly rather than relying on engine gunk.

Re: Official Oil change discussion

well thats an individuals error, not corporates.
im just as bad, i dont trust pepboys because theres always a new issue after they touch my car.

Re: Official Oil change discussion

I wouldnt do it in my car. and I dont trust Jiffy lube anymore. not after my oil pressure sensor got screwed up after an oil change with them.

Re: Official Oil change discussion

ive never worried about it. and according to the jiffy lube certification training course thing i had to go through for a week, its fine to do and will not harm your engine at all. the "real" mechanic i worked for as well taught me this too. i say "real" because jiffy lube isnt exactly full of real mechanics. but i worked for monro.
lack of performance and other undesirables may occur, but harm and damage is not on that list.

Re: Official Oil change discussion

well I wouldnt mix standard oil with synthetic oil, or mix the oil weights, but mixing the same weight of oil across the brands and same class of oil is fine.

Re: Official Oil change discussion

you can switch to any oil and even mix oils without flushing the engine. dont let anyone tell you otherwise
also, not so much with your g6 but becareful when using seafoam on older cars.
my grandfather who was a mechanic for a long time always told my dad "if the engines full of muck and dirt, keep it that way. its plugging something"
i seafoamed my 95 grand cherokee and opened up an oil leak in the rear main seal.
and deep creep is amazing, works wonders.

Re: Official Oil change discussion

i think that's called seafoam deep creep. i used it with a toothbrush to clean the inside of my throttle body.

Re: Official Oil change discussion

I've read they make a spray too, that can be "attached" to the intake boot and sprayed into the intake while the car is running rather than using the PCV valve. Is this true as well?

[snowmanG6]

Re: Official Oil change discussion

yes, but have to get the proper measurements for how much to add to the oil and how much to add the to vacuum line. yes the one attached to the brake booster. all the instructions are listed on the can.
this is what the can looks like

Re: Official Oil change discussion

So a full can on the fuel tank (I assume on a full tank). Then what half a can in the oil and the rest in the PCV valve (I assume the line coming off the brake booster?)?

Sorry if I am not the most technical of all users, but I just want to make sure it runs well, and is in top-notch shape.

Re: Official Oil change discussion

And it is safe, obviously you wouldn't recommend it if it wasn't, but I am not exactly an expert like you guys so

I have been using it in my car for a about 2years now. I dump a 1 can into the gas tank. and another can to put some into the crank case (I do it close to an oil change) and a little in the vacuum line. there are also tons of older guys who have been using it for many years. oldmanvette1975 is the guy who turned me on to it

Re: Official Oil change discussion

use Sea Foam. its the best stuff out on the market for cleaning engine oil, fuel injectors and a bunch of other stuff. you can pick it up at wal-mart or your local car parts place.

Re: Official Oil change discussion

nope.

I thought so... even saw http://www.nbclosangeles.com/news/lo...hservices.html seems like a bogus recommendation. Though the fuel system cleaner scares me... I have been using those in my cars since I was able to drive....

Re: Official Oil change discussion

Switching to synthetic oil on our G6, a friend of mine told me I needed to "flush the engine" once I drain the old oil for 20 minutes or so, before adding the new synthetic oil... Is this true?

nope.
