Conventional oil hard to find?

I follow the guidelines in the service manual that came with the car.

Following that book I've been driving my 1990 as my DD but since you're worried I will tell you that for insurance against attacks by tigers I've also carried an amethyst talisman in the trunk next to the manual.

Haven't been attacked by a tiger yet so like you say it must be working.

Other than replacing the fuel controller and fuel pump from that same trunk a few times already and having to jack up the engine in front to replace the plugs that Q45 still works fine using just the maintenance service interval recommendations of an oil filter every other oil change as specified in that three inch thick service manual that came in the trunk with every vehicle sold and which stows neatly next to the talisman to ward off evil spirits.

Haven't had to replace the engine yet so like you say it must be working.

Why don't you believe what is found in many service manuals and what I have in my hands right now? I have other service manuals but why would I even look in my other service manuals if you won't believe what I am telling you to your face is in my 1990 Q45 service manual (one came with every car).

BTW, don't know who Arlin is but do you want me to take a photograph of my three inch thick green paperback service manual which came with my 1990 Q45?

Tell me where to upload it for you and I'll upload for you page MA-6 which shows a "R" replacement for the oil change every service interval and an "R" replacement for the oil filter every other service interval and an "R" replacment (with "I" inspections in between) for the air filter every fourth service interval (based on kilometers/miles and/or months, whichever comes first).

But why don't you first look up what you make up before you spew it anyways?

You realize you are talking with Arlen Holder...

You have been watching U tube vids. Stale ones. How often do you change the saw on the Dremel? Does that put metal shavings in the oil?

Arlen won't see this because he has me kill-filed, thankfully.

Remember the old oil filter trick where you just use a roll of toilet paper? I thought I'd never see that again but it turned up on an episode of Garage Squad.

Pleated or non-pleated? Cardboard or steel end-caps? He filter level is <0.

Was that the link that you intended?

From that article: The cheapest insurance for your car’s engine is frequent oil changes — with a new filter at every oil change. That prevents contamination of your new, clean oil from anything that might pass out of your old filter and ensures that new oil is as efficient as it can be in its job of lubricating engine parts, reducing wear and tear, and keeping operating temperatures in a healthy range.

If you’re wondering how often you should change your oil filter, keep things simple by changing your oil filter every time you change your engine oil.

Looks like it's a new filter at every oil change. Seems simple enough.

Don't believe that. Arlen was never an accountant.

Evil twin? It's Arlen he's whatever he wants to be to suit his purpose.

I've owned 25-30 cars. Every one specified oil and filter so that is what i do. If you have different, fine follow it. Simple.

Nah, Mike is polite. Arlen does not like at all and thinks I post under at least five names.

No, you're not following the guidelines in the service manual. Because if your car was made in 1990 then the oil described in the service manual is no longer being manufactured.

Is the current oil better or worse than the oil that was originally specified? It's likely much better. But you don't really know. All you can do is drive and hope.

There are some cases in which the current oil formulations may be problematic for older vehicles. 1990 isn't old enough to worry about, but some people drive vehicles where they might worry.

Considering the TP shortage we had I'd not be surprised if people were unraveling filters to use in its place.

Maybe he's taking his meds. He has me blocked and other forensic details lead me to believe it's Arlen. You noted a discrepancy along with a different vehicle so you may be right.

Whatever, he can get blood out of stone with his posts.

The problem with that line of argument is that modern cars last a long time even if you don’t bother to do that oil and filter changes at the specified frequency.

Problem is what constitutes proper maintenance.

Very unlikely to see the engine die if you don’t do whats specified. All you really need to do is check it hasn’t run out of oil and water.

Only if your don’t understand the basics.

Now you're just being silly. Every car ever sold specified the current oil spec as the guidelines.

We've been at this since round about API SC days as I recall (do you?). As I recall when the emission stuff hit the fan we jumped all the way to SD.

It's been that uphill climb ever since for every vehicle sold in the USA.

I pulled out my shop manual for a 1997 Japanese vehicle and it says on page LU-1 "API grade SH Energy Conserving if multigrade engine oil or ILSAC multigrade engine oil SAE 5W30 is the best choice for your vehicle, for good fuel economy, land good starting in cold weather." On page LU-2 it says to use 5.4 liters (5.6 US qts) with oil filter change and 4.7 liters (4.2 US qts) without oil filter change.

It even specifies a "Dry Fill" on page LU-3 of 5.8 liters (6.1 US qts) which I don't remember if I've seen that in other service manuals (have you?).

Looking in a 2002 German factory manual on page 020-10 under "Maintenance" I see my own handwritten note to not to use LL-04. On page 020-6 are the "Maintenance Tables" and here it says to change both the oil & filter for Table a. Oil Service, and the same for Table b "Inspection I Service" and Table d "Oil Service" it says in the chart to use 7.5 liters (7.9 US qt) of

5W-30 synthetic oil BMW part no. 07 51 0 017 866 (LL-01).

Stop being silly. It gets better with each designation. Sometimes it matters. Sometimes it don't.

Stop it with the silliness. It don't get worse for motor oil or for oil filters.

I don't know why I'm bothering to pull out my manuals just because most of you pull all your statements out of your own asses instead of the manual.

You made me go back to my trunk to push the talisman aside (to ward off those tigers) and on page MA-9 it says to use 6-3/8 qt (US measure) with oil filter and 5-7/8 qt (US measure) without oil filter and in the "Recommended fluids" column it says "Energy Conserving Oils of API SG asterik 2, asterik

2. Asterik 2 For further details see Recommended SAE viscosity number (MA-10) Asterik 3 Energy conserving oils. These oils can be identified by such labels as EC-I, EC-II, energy conserving, energy saving, improved fuel economy, etc.

On page MA-10 there is a viscosity chart with the captain of "10W30 is preferable if the ambient temperature is above -18C (0F). 20W-40 and 20W50 are usable if the ambient temperature is above 10C (50F) for all seasons.

Anyways out of three factory manuals the two Japanese manuals specify oil without filter and only the German manual specifies the oil with the filter every time.

I don't know why I bother to dig these up just because most of you pulled your comments out of your asses which is why you're wrong on all counts.

In the end (given that's where your ideas come from) you can change your oil and filter on any interval you like but stop making up shit about the factory specifications please.

Two out of three of my own shop manuals refute everything you people claim.

Yes. Of course it was.

I think I'm the only one who isn't pulling all his ideas out of his ass. :) All my statements were backed up with relevent articles and shop manuals.

That link you read said exactly what I said that link said. Actually I gave you two links which both said what I said they said.

Please read both links again and let me know what you found when you do. What you should find out is that both said exactly what I said they said.

I suggest you search for what it says about manufacturers recommendations. :)

Some americans have claimed to wipe their ass with their cat.

The dutch whine a lot, but have never had a problem wiping their butts.

The links are a bit contradictory.

First link says: If you’re wondering how often you should change your oil filter, keep things simple by changing your oil filter every time you change your engine oil. Following this schedule might cost you more money, but it will save your engine from possibly getting clogged with grime, sludge or large metallic pieces.

Second link says: Many manufacturers say to change the oil filter every other oil change. So, if your owner’s manual calls for oil changes every 7,500 miles, that would be an oil filter change every 15,000 miles.

But a lot of owners and mechanics — many of them the same people who would never go past 3,000 miles per oil change — also would never dream of doing an oil change without also changing the filter. Their reasoning: Why pass brand-new, clean oil through a filter that’s already carrying gunk from the old, dirty oil?

I just follow my manual that says every change. If yours differs, fine, follow it.
