That little dog is a warrior Bob! Those lizards give me the creepie crawlies……..
Fred, I'm not a fan of many cold blooded animals. Looking into their eyes doesn't give me warm fuzzies.
I'd take a falling iguana over a rattlesnake in the deep grass any day!
I'm not saying I'd want the iguanas either
Marc, I have to agree with you. The deadlier the cold blooded animal is, the more I feel like eliminating them from my immediate presence. Also, Jasmine might get a bad scratch from their claws but I don't think an iguana could kill her. Alligator, crocodile, rattler, moccasin or copperhead might give her a run for her money.
meh unless it can give you the viscosity and the chemical make up, testing beyond feeling for grit is kind of a waste.... unless its a device I would trust.
Id rather see how much oxidation is present and what the add pack levels looks like? Has it started picking up wear material from bearings and such if im gonna go through testing.
Transmittance is a UV light test, so the minute clean oil comes in contact with the residual oil/carbon deposits in the engine its gonna show a false degradation.
Adam, I agree. I'm just going to start the process of changing the oil in all three cars.
LOL I suppose you're right! I have dispatched so damn many buzz worms, I'm probably more used to them....we severely lack in trees, so no worries of them dropping on ya .....
Fred, living where I do there's lots of things that can kill me. There are lots and lots of coconut palms in Florida. A falling coconut carries enough energy to kill a person so I steer clear of them. It' a half-mile walk to the Brightline passenger express station. Trains and I have some negative history.
"Brightline ranks number one in terms of the number of deaths per mile traveled. Statistics show that for every 37,000 traveled by a Brightline train, it experiences an accident that results in a fatality. The figures are staggering, and the next deadliest train on the list does not even come close. For context,
San Francisco’s CalTrain, which is second on the list, experiences one fatality for every 105,000 miles."
Bob, for less than that kind of money, you can get your oil tested at a lab! Well, one sample.
@Squankum, I would spend money on lab tests if there were any signs of oil-related problems with my vehicles. The '87 Corvette is the highest mileage one, with 87,887 miles and the only oil issue left since I replaced the valve seals is the front seal. In the 33 years I've owned it I've never needed to add oil between changes.
Bob, I'd worry about additives settling out after that much time. Please see the video I posted at my thread last week by nerdy-son-of-Lake-Speed. I'm having a situation with the rear axle on the Durango lately and Mobil 1 gear oil that I bought in volume to save money then it sat for years may be a culprit. (355K mi may be the other very likely culprit.)
Then again, you aren't driving it yet, so I'd wait until it's all fixed up, then change it.
OK, the differential fluid in the Corvette is due for a change. I've never changed it and although there are no signs of any leaks I am still planning to do something about it. There's no drain plug on the differential and there is no simple cover to remove. The differential cover is part of the batwing and is a nightmare to remove. The FSM diagram makes it look simple:

The reality is more complicated, requiring removal of the transverse rear leaf spring, upper tie rods and spindle support rods.

Of course, none of that stuff is accessible until you remove the exhaust system and spare tire carrier.

I bought two solutitons: 1) a suction pump and 2) a drain plug kit.

The suction pump may or may not fully drain the differential but I plan to try that first. If it doesn't remove enough fluid or if there appears to be metal dust, I will use the template to locate the drain hole to make me comfortable, I may
Bob, you could always send some oil to Chris Elliot for testing.
(My memory swears that this ongoing bit once included conventional vs. Mobil 1 motor oil but I can't find it. And Don Giller, the YouTuber who apparently has an archive of all of the Letterman shows and makes compilations of them, doesn't remember it.)
I would normally trust Chris Elliot but since his passing from brain cancer in 2002 I've relied on others for my oil-related questions. There seems to be a curse on my oil expert club since Vito Corleone passed in 2004.
