When is a good time (miles) to change out the break in oil?

 

Mr. Mom....

There is NO BREAK-IN oil in your HHR. GM, nor many other vehicle manufacturers, haven't used "break-in" oil in years......and I mean a lot of years. So, that's a total myth .


And for the other myth posted here....you can use synthetic oil from the get-go in your HHR. See this posting from GM, I did a while back.....

The HHR has the sensor that tells you when to change your oil. How many miles does it run before it tells you to change your oil? Lets see we bought ours with about 20,000 miles and around 90% oil life and at around 29,500 it said to change the oil. So it must be about 10,000 miles or so. Sounds good to me. I think I'll stick with the indicator thing!

 

There is no sensor that contacts the oil to determine how good it is. The OLMS is a sophisticated computer program that was developed over many years by GM Powertrain engineers. This system takes in many variables, mostly running temperature, speed, and time, and computes the remaining oil life based on conservative tables that were developed by testing modern engine oils.

LOTS of great information.

 

LOL! You put the oil in that cap marked 710 on top of the engine

 

Almost TOO much info....LOL

That is a great post....debunked a few myths that I still held fast...

BTW...the dealers service mgr told me to run the stock organic for 2000 miles
before switching to synthetic....who to believe anymore....

it s amazing the differance that two years makes...

not sure that Mobil is the reason that people were changing oil at 3/3000... car manuals... most mfg for years said to change and service at 3/3000 more often under HARSH driving conditions.

not all oil filters are mfg by a single company (i think i found at least four different mfgs two years ago)... even so... two filters mfg by the same company can have different specs. just going to have to dig a bit to find out who and how they are made... I currently use K&N oil & air filters... might use mobil 1 extended oil filters if they were ever in stock.

oil change intervals... two yrs ago i bought into the chevy dic oil life remaining... made good sense... back then about 90 percent of the opinion favored 3/3000 and i was the idiot for trusting/using the dic. well with over 20,000 miles, i have had two dic scheduled oil changes... thats a lot of bucks saved... the only unscheduled change was at 1500 miles (break in) and to switch over to mobil 1 syn.

just serviced my K&N airfilter 20,000 miles... early by K&N recommendations... could have gone another 20 or 30K. the filter was about 50 persent dirty. did it now because i was doing dress up on the shrowd.

i am sure as the cost of oil goes up there will be more converts from the 3/3000...

i change oil on my older engines... sb350(1970) and sb283(1957) more often than 3/3000... they are really DIRTY running engines... lots of blow by... moisture and particulate... todays engines are much cleaner running and can handle the extended life syns...

like i said what a difference a couple of years makes

 

magnets...

two yrs ago i stated in a forum that i placed a very strong magnet on the oil pan or oil filter (if it was metal) to trap metal shaving/particulate...

the coment then was... "how does that work on an alumimium engine" anyone care to comment?
