Home Forums Hunting & Shooting Hunter's Campfire How Often Do You Change Oil?

........................3 months ago after all of my free bee oil changes (done every 6K miles) were used up at the dealer where I bought my 2015 Ram Hemi brand new, I started using 5-20 AMSOIL Signature series along with their appropriate long range oil filter.......$12.30 per quart x 7 quarts is $86.10, plus the filter at about $17.00 from the local AMSOIL distributor, plus $22.00 to do the oil change where I go. About 134.00 total every 15K vs $40 to $50 each time every 5K.........Cost wise, it is almost a wash.

Oil w/filter changes now at every 15K miles.

It's all relative.

The truck/cars get it 2X/Year - I throw the inspection guy a bone and do it myself in between.

The Mule gets it every 100 hours.

I've had a Craftsman push mower since 2002 and have yet to even bother to check the oil.

Whenever the odometer hits the next even 10k +/-. Mobil 1. 180k so far, but I'm pretty sure I could get 200k with the used Mobil 1 I pull out of the wife's car.

Maybe at 400k I can say the 10k was a good idea. Hard to say in a Toyota, does anyone actually wear one out?

I leak out a quart a week. Mine never needs changing.

Last two Land Cruisers I change every 15-18k miles... syn

Depends on your definition of "wear one out"

I change them on the schedule the owner's manual recommends. That means every 7500 miles on my 99 dodge/cummins, 10,000 miles on my 2014 camry, and 5000 miles on my 2016 tundra.

Where I live there is always dust in the air....maybe even when it's raining........3k-5k max.

5K on the Tundra, Ford F150 and Suburban with plain old oil.
10k on the Porsche and Audi with Mobil 1.
3k on the '73 Mach 1 with Royal Purple.

6K Dodge Cummins, 15K for the big Cummins, 14 gallons for that beast.

10k or once a year for 4runner.

Grew up working in my uncles gas station garage and was firmly taught to change my oil every 3k, did that for years and had great results.

When I bought a new 4x4 in 2004 the manual stated 4500 and I have done that using standard oil for the past 315000 miles, again with great results.

Have a 2018 4x4 on order and it will be my first car to run synthetic oil.

if Mobil 1 is as good as they claim I will be happy.

didn't know know the dead needed an oil change

My new truck came from the factory with synthetic everything. It calls for the oil to be changed at 8k miles or once a year which ever comes first. It has a warning that comes on when it's about do. Bing that I have the lifetime powertrain warranty I take it to the dealer and have them do it. Off to see them in the morning.

NYH1.

As always I'll get flamed.... but what the hell, its the campfire!

I run mine anywhere between 4 to 5 times the distance as you do your 5K changes...

or between 3 and 3.5 times longer than you run your 7K changes...

Napa Gold filters, change every 10K.. oil used is Mobil One...

pretty much have been using Mobil One since about 1985, almost exclusively...

Oldest vehicle I have is my old 88 4Runner bought new in Sept 87... its had
Mobil One pretty exclusively most of its life... she's got a mile or two on her
and still chuggin around pretty good...but does show some wear here and there...

good man! that's the secret...

but don't tell anyone else about it...

some of these weiners might get pissy again...

they hate people who change valve cover gaskets..

ruins the environment or something along those lines....

or so they say so...

or maybe that is one of the key causes of global warming...

too many used Valve Cover Gaskets laying around, ruining the ozone...

every 5 thousand miles. Using regular 10W40. Pushing 400K miles now

5k on the Powerstroke, along with a tire rotation.

Last change for my 2006 GMC Sierra diesel was in July 2016, I'll hold off changing it again until the oil analysis recommends another change. Using Amsoil Series 3000 5W-30 HD Diesel Oil (recommended for pre-2007 diesel engines), with an Amsoil Remote Dual Bypass Filter System. Tested every 7,500 miles and never once had a report that even came close to recommending an oil change. The dual filter with a high efficiency bypass filter changed every 50k miles, or upon second primary full flow filter change every 25k miles, keeps the oil clean. Even soot contamination after 21,000+ miles remains under .1 of 1 % of volume, same for oil fuel dilution, and viscosity thinning from sheer. The additive anti-wear metals always remain well above minimum concentration, and the viscosity remains constant. While the DuraMax engine is thrifty on oil consumption, the small amount of makeup oil replenishes the additives sufficiently to maintain viability. Given the new oil required at filter changes, I may never have to change the entire fill of 10 quarts + 2 quarts for the filters, again. Given that I keep the extended warranty current, maintaining used oil analysis records is required should anything go amiss.

I also run a Baldwin coolant bypass filter along with Amsoil Propylene Glycol Antifreeze & Coolant, to protect the cooling system. After the first annual filter change I found the filter media had trapped considerable residue of engine block casting sand, scale and what appeared to be flecks of gasket sealer. The filter will also trap any products of coolant breakdown, that white concretion that plugs radiator tubes causing overheating, This coolant is rated 150k miles or 5 years in light vehicle applications or 600K miles 12k hours or 6 years in heavy duty applications.

The book sez 7500 for my truck, unless it's being used in 'severe duty' (or similar) which drops the mileage to 5000 between changes. Using Mobil-1 diesel synthetic.. I'm sure I could go longer, but oil's TONS cheaper than a new engine..
