Whoa!!! hang on there!! Thats 5w30????? These motors require 10w30!

Well, I use 10w30 Mobil one synthetic. My motor runs very well, and I mean, very well. Transaxle shifts wonderfully, locks up, and stays locked. Not bad for a car with 278,000 kms on it ehh?


But I recommend using the factory 10w30 specs. Or maybe going to an even higher grade, like 15w30 (if there is such a type avalible.)

naw, our motors use 5W-30

87-89 motors say 5w30 90-91 motors say 10w30. Either way I wouldn't run 10w30 in the winter, 5w-30 all the way.

I run 5W-30 Winter and 10W-30 In the summer. Its the way things work. :D

Update on the engine:

I changed the oil IMMEDIATELY after getting home from some high speed highway cruising...let me just tell you something. That oil. Was. Hot. :lol: Let it just be known, NOT to do that.

On the upside, I got it all out without any serious casualties and then refilled with the Mobil 1 and Slick 50. WOW, that slick 50 looks like goopy vasaline! :lol: I never woulda guessed.

But the news is that right after I started it up it started to tick, but it went away almost IMMEDIATELY, it was good. It is actually running QUIETER allover than it did before. Its great. AND, im not sure if its kind of a placebo effect of the slick 50 or something, but it seemed to have a little more get up and go! It was good. And if anyone is wondering if I let it work in, I ran over to the adjacent town for a bit and kept it running, so it got worked in for about 30 mins and then a bit more. So at least I know its REALLY worked in there. So anyways thats what is goin on now. I am waiting for it to be really cold again to take a new video of that lifter. We'll SEE!

Thanks for the help with this guys, it really is appreciated.

just getting caught up on my reading. i noticed you were commenting on the slick 50. when my bonneville still belonged to my aunt, the first winter she was down here i started servicing the car. i noticed in winter a fast clatter on a cold winter morning from start up till about the 50-60 second mark. asked the garage and he recommended slick 50. put it in the next oil change. that would have been winter of 2003-2004. it just started ticking again this winter, which is about 30,000k(18,000m?) later. the car uses about 1 litre of 5-w30 between changes which is about every 5,000k(3,000m). i'm going to get a can of slick 50 tossed in next oil change. i figure one can every couple years can't hurt and seems to help.

For high mileage engines they recommend one at every oil change.

i wouldn't disagree with you but my wallet begs to differ.i try and take care of my cars but i'm also cheap! when it starts to tick again we'll throw some more in. ;)

I can understand that, I'm in the same position.

But I will say that if this is ends up stopping my lifter from ticking, then that would mean it is lubricating the crankcase MUCH more efficently than regular oil, or even synthetic oil for that matter! If it does make it go away, I think I will be sticking with this product for many oil changes to come. We'll see!

Now we're just waiting for another very cold morning to take that "after" video.

The regular slick 50, exactly like the picture you sent me John :roll: Not the high mileage one ... lol

The standard one should say add once about every 50K miles.. It's not overly thick either.

That garage sounds awfully loud :lol:

As with the 5-30 in the winter, I agree. You don't need to worry about viscosity like you do in the summer
