Easy but always asked question
Quick easy but I know...always asked kinda of question
87 Bronco EB, 302.. Live in Canada (Not that cold guys...hahahaha)
I have an oil leak.. the guy that sold the truck told me to but 20w50 oil at summer and 10w30 at winter...
With a leak, will it leak more with 10w30 or 20w50 ?
And which one should I really choose ? 20w50 or 10w30 ?? And for Winter ?
Easy Eh !
hahahah
Thanks guys !

ok, the 20W50 is a very heavy oil, in summer, it would definatly protect the engine better, because it will thin out in the heat, but in winter, that think oil will thinken, and in canada, im sure it gets plenty cold, that puts a terrible strain on the oil pump, and will take longer to provide lubercation on cold starts.
the 10W30 is the recommended oil for our vehicle, right from Ford. i beleive that they would intend for us to run that all year, but in my opinion, it is kinda light, i use 10W40 in my '91 302 all year, i use Quakerstate High Mileage( i have over 135,000mi on the truck) and i love it.
just my two cents

Hurley - I'm a Canadian too, eh. Run 5w30 in your truck all year round - it provides the best lubrication in all weather conditions. Switching the oil back and forth doesn't do anything but annoy the hell out of me on my vehicles. I read a bulletin from Ford a while back that stated they reccomended 5w30 for all their vehicles from the 80's up. As our temperature in the summer hardly ever exceeds the 35C mark it works fine. I haven't had any trouble in my 88 or 89 from the oil.
The rear oil pan leak you are seeing is either your rear main seal, the oil pan gasket, or something is leaking down from above (intake gasket at the back).

Just changed the intake gasket...its probably the main seal, always had the same problem with all my Ford Trucks... and that or the oil pan seal is a pain in the ****....so for now I think a will let it go...till I can do it properly...what do you think ? 5w30 isnt it to thin, that its going to leak even more ?

If it's leakinglots there is no oil that will stop the leak. As for the weights of oil I wouldn't go too heavy on the oil for the winter. I think a good 10-40 high mileage would work fine for you. But I would try it. You have nothing to lose, but a bit of oil right?

it really doesn't matter when we're talking these type of engines. 10W-30, 10W40, 20W50.....the motor will run fine on any one of them. and BTW, the "W" in the oil grades stands for "Winter".....and Bimmer is right, nothing will stop the leak, so you either have to fix it, or keep adding oil....either of which if fine!..lol I run 20W- 50 all year round in my V-8's.....it's a little thick, but my big block from '68 doesn't seem to mind it one bit!

I run 10-40 in my car and truck. It seems good to run here in texas, provides good protection from the texas heat. I am running castrol GTX start-up 10-40 now and i have had great luck with it. If you want to wonder what my credentials are living in Texas and all. I used to live in Canada. We ran 10-30 in our trucks year round with no problems. Also we had a 89 302 f-150 and it leaked almost from the factory from the rear main. If you own a ford it's just something you have to deal with.

If you are concerned about oil pressure get a good mechanical guage first. The stock guage is worthless. I will never again use 20W50 even here in Texas in anything. Having done some tests, it took twice as long to get good flow from startup as 10W30 even in Summer 108 degrees. Oil pressure after full warm up was about the same. I use Mobil Clean High Mileage 10W30 for my 174k miles Bromco year around. A little cat litter on garage floor pan works great for the drip. BTW the first 152k miles had only 10W30. The leak started when I changed to 20W50. Be sure to check the oil plug seal for a leak also.

Awesome guys... If I have to add some, should I do a full oil change to put the 10w40 or I can add some with the 20w50 that I already have in the engine... I`ll eventually do the full oil change, its due in about 2 month...but for now, for today lets say...doesnt matter ?
And yes if you own a Ford you have to deal with that stupid main seal leak !! 2 Ford Trucks...had all the same problem!

i don't agree with that.if theres a leak then something is wrong.i've even dealt with pontiacs with a rope rear main and properly installed these won't leak either.

H U R L E Y I would add 10w30 as needed but everyone has their preferences. I just think the sooner you quit 20W50 the better. The exception being an engine so worn you think each trip may be the last. 10w40 has one of the challenges that 20w50 has. It has a range of 30. I guessing that asking the chained molecules of plastic to hold up and expand like little springs when hot for long is easier with a range of 20 as in 10w30 plus with greater flow you get better bearing cooling both at startup and at extremely hot conditions.
