I assume it's always hot down there so that's what I'd be using.

Maybe 10-40 in the winter.

Conventional Valvoline oil works for me. 143K

Wow, 20-50 and 10-40 in the winter? I've used 10-30 and 5-30 in the winter and had no problems in 15+ years. Is anybody else using oil that thick on a regular basis? Just curious.

I'm about to do my oil change and go to 20w-50 cause its always hot down here. I'm not even 2000 miles into my last oil change 10w-30 and it is done!.

gndriver,
If your oil is done at 2000 miles can I assume you are using dino oil and not synthetic?

 

[gndriver]

Thats correct. I have been running 10w-30 for the last three years down here and it doesnt last before its broken down. Up in north carolina i would use 10w-30 but it gets to hot down here and the humidity is worst than any other place I have been to. I talked it over with a good TR mechanic and he's been running 20w-50 for a couple of years. So I'm going to try that. Having to change your oil every 1500 - 2000 miles gets tedious.

Just to be clear in the summer I use 10/40 and in the winter 10/30. Up here in CT.

In sunny FLA. I would be using the 20/50 and 10/40 grades.

oil

If you email any of the oil companies they reccommend 10w30 and not 10w40 winter or summer.Bruce

I use nothing but Mobile 1 5w50 down here in GA. Always synthetic in everything I use. Hell I even put it in the riding mower.

mobile one

Ive used mobile 1 15w50 ever since i can remeber. ever since the car went over 70,000 miles or so. its at 135,000 with no problems, the only thing i have replaced on the car major is the timing chain and powermaster unit..

Grade of oil

If you have any leaks, dont use synthetic. I'm a big believer in Kendall 10-40. That's what i use in my 87 limited. Nothing wrong with synthetic stuff, but i dont want to spend 4 or 5 bucks a quart for it.

leaks

if u have any leaks? If you have a leak like a rear main or something then fix it.. if you have oil consumtion then use a heavier weight oil. aka 15-50 20-50 kyndal makes a 20-50, kyndal is a good motor oil. Id always use regular oil after a rebuild or after you have had the motor apart. just for break in etc. but after 500 miles id always put synthetic in. just me i guess
