Strange oilpressure gain---

Earlier this week, I went downtown on some business, and since we are running out of "roadster weather" I took the roadster pickup. The business concluded pretty damn quickly--(the automation house I went to see had gone out of business 3 months ago---nobody told me.) Anyhoo---There was one of those "instant oil change" places right beside the place I had went to see, so I decided to get an oilchange, grease job, and new oilfilter on the RPU. Ya, I know---goldchainer or what!!! They did all of the requested tasks while I stood there and watched. The new oil was 10W30---same as the old oil (which had about 6000 miles on it, since I built the car.)---Now remember---I never even unbuttoned that old 305---just pulled it out of an old '85 Pontiac, washed the dirt off, and painted it and put it in the RPU. I did put new oil and a filter on it then.--That old motor has umpty-ump miles on it. When I drove away from the oil-change place, I immediately noticed that instead of the 25 pounds of oil pressure which was always the norm, I now had about 45 pounds of oil pressure!!! Okay, I figured---the new oil is cold---it'll be a little thicker---thats probably normal. Then after driving around for an hour, I notice that the oilpressure is still setting about 10 pounds higher than it ever did.:LOL: :LOL: :LOL: This is curious---Maybe the kid used rear end grease instead of 10W30???? The engine seems to like it----Runs fine---runs at the same temperature---starts the same as it always did. What do you think???---Brian

Oil filter bypass isn't releaving as soon as it did before. Other filter was either plugged or defective. That's my guess.

That's that new oil change place that rebuilds you motor while they change your oil.........all for $ 29.95 !! :D :D Did they also have doughnuts in the waiting room? :LOL: :LOL:

Going to an oil change joint with your hot rod?

You're a braver man than I, Gunga Din.

Every single time I've gone to one of those places, there's been a problem.

Broken Zerks about three times in a row on my old 77 Ford 4x4.

Stripped pan plugs in both of my purchased new and maintained by me except for the one time at the oil change place 88 Mustang GT and 89 Ranger 4x4.

The broken zerk place was an independent, but they were always telling me I had a broken zerk.
Probably their little way of making a couple extra bucks.

Walmart was the place that stripped the pan plugs.

Thank God Ford makes a plug that's softer than the pan threads.


I thought for a while that changing the pan plug to a smaller hex would help keep novice mechanics from stripping the plug, but not so.

Nothing quite like watching a guy hanging on a long 7/8" wrench when tightening the pan plug.
Better yet was watching him try to explain his stupidiy to the customer who'd just watched him strip the plug threads out of the pan.

Surprising how many 'stripper' plugs you find in old engines.

Changing oil is a pain in the backside, but in the end it's easier than repairing the damage done by people who don't care if the customer's engine is damaged....

Don---No donuts, and it cost $51 (which is the same as I paid at the Ford garage this morning for the first oil-change on my new Ranger). C9X---the key words were "while I stood there and watched". Actually, I've never had a problem with one of these "instant oil change" places other than the cost.

ps: Or you had 20w in it before, and didn't notice you switched the bottles. :LOL: :LOL:

Denny---you could be right. The older I get, the more I do that kind of thing.:CRY: :CRY: :CRY:

Denny's got a good point.
Strikes me it would be easy to select the wrong fill gun and stick in an oil brand/grade other than what the customer wanted.


$51.?

That's in Canadian dollars?

I hope so.

C9X---Yep, thats Canadian dollars---But as of about 2 hours ago our Canadian dollar was worth MORE than the American dollar. and yes, thats what an oil change and filter costs, at a dealer, or at a "Quicklube".

they have to pay the heating bill during those canadian winters

i used to be one of the oil change boys a few years ago.... i noticed unlike me, the other guys were just doing it as a job, i was doing it because i was going into automotive as a career, the ones that are just doing it as a job are usually the ones that break stuff.....
