Oil Change

[Sharkus29]

Hey guys, so I changed my oil last year at the beginning of summer. Over the summer I put maybe 1500 to 2000 kms on my GTR. It's not a daily driver it's more of a weekend warrior. Now it's been in my garage all winter, which is heated. I was just wondering what your thoughts are as to if I should just go ahead and change the oil again, or if it will still be good for a month or so come may when I bring it out? Thanks

change it. better to be safe then sorry... just change it, maybe what 40 bucks out of pocket to make sure its good oil... just make sure you do it before you go to start it... so if you arent planning on starting it for another month, then leave it and do the change before you start it,

Unfortunately my oil changes cost me over 100 bucks by the time I get the oil and filter. But yeah I'll just change it when I'm getting ready to take it out. Thanks

Why does it cost so much? I get the oil filter from local napa for like 8 bucks, and the oil for 40-50 in big jugs.

I replace my oil twice a season (put on anywhere from 1-3k)

Imagine those of us with more than 12L capacities using Motul or Royal purple

Oil will absorb moisture over time. Even with little to no mileage, the heat cycling is enough to create condensation. General rule of thumb in the industry is 3 months or 5000kms, whatever comes first.

I use Royal Purple so it's not cheap!

My neighbor is a older guy and he changes his oil every 3-5 years cause its synthetic he says.
He drains the oil every spring to inspect it then puts it back in and just changes the filter lol. His Supra still running for some reason.
How is this possible?

I was wondering as well,i did oil change ,600 km ago in September,put it away in October,i was doing some research online here and there,many people who put their cars away for winter,either change their oil before storage or after, once a year.

I always do mine pre-season. Irrelevant to last seasons usage

OIL;
conventional - is full of minerals, and breaks down rather fast and stops protecting the metal surfaces due to the gas, and heat breaking it down. this is why you must change conventional so often. with in 1000km you have 75% protection

also, due to the gases in the engine non-use still degrades oil in 3 months (3,000km)

conventional will be removed from market and only bleanded will be massproduced as the basic oil

blended- exactly how it sounds a mix of syn and conventional oil between 50%-75% (5,000km)

degrades with non-use in 6 months

full-syn- no less then 75% synthectic oil.- synthectics dont break down. the detergents do. 6months - 1 year (7,500km)

100% syn- is 100% syn. contain no oil which breaks down, and higher grade detergents which are rated for longer periods, at heatewr temps.

can last for at least 1 year with non-use, and manufacture graded kilometers (up to 75,000km)

most recommend miles as regular service, but this is canada an extreme service climate so just swap mile for km. and replace often.
its your engine. oil is cheap insurnace.


so in answer : yes change your oil out of storage no matter the km. youll thank yourself after years of reliable use.

clean oil at start of storeage is good because then your engine has 100% protection from the oil all through storage.
if you store on dirty oil then your engine is bathing in a mix of carbon and gas and is suffering internal corrosion that you cant see.

with blended.... and the standard is 5,000 miles but we are in extreme climate so 5,000km instead
