vintage oil

[Ford428CJ]

I would rather use a newer oil. Much better than the days of the old per say. You can find high zinc stuff and the additive packages are so much better then the 80’s. JMHO

   Thanks for the feedback guys. My lawn mower will love this stuff!

My lawnmower cost $3000, it gets full syn and regular changes.

That's cheap! Our lawnmowers at work cost from $16k-$90k. Yes, that's 90 thousand. 
My home mower is almost 60 years old and gets 30w non-detergent. One of these days it just might need rebuilt

I'm likely familiar with that $90K mower.  Fellow I built those Willys for had a couple.   Big bastards, like 20ft cut with three folding decks.  Can't recall the brands, he bought them used.  With 11 acres to mow, he needed a big mower.

My early 70's vintage Cub Cadets do just fine LOL!!
My 149(14hp) is still all original, untouched, and doesn't burn a drop of the 10w30 Valvoline I run in it(yes, it's detergent).  Doesn't seem to bother it even though I run it a few years before changing it.  My 127(12 hp) got a rebuild last summer because it was plum wore out when I got it.  It runs the same oil with little fuss.

I’m old enough to remember when Mobile 1 came out in standard card board qts, soaked  through in about 90 days on the shelf. My Dad switched as soon as the rep came to the shop,he was an air cooled VW guy and loved the stuff.
Then for years Mobile 1 coming in steel cans.

Would be interesting to compare the single grade Mobil 1 oil to the large product range of Mobil 1 products now.

When Mobil 1 first came out, even new vehicles at the time dripped out lots of oil right from the start. Older cars with high mileage actually came into our Standard Oil station with hardly any oil in the pan as poor gasket and badly fitting valve covers and pans leaked it out very quickly. Today, better designed engine components and improved sealing adhesives and gasket materials have most car/trucks not leaking any oil at all.

Which reminds me. First Gen 1950's-1970's SBC's leaked oil terribly with even heavy weight dino oil!

Our biggest mower is an 18' Toro with 3 folding articulated decks, a turbo 4 cyl diesel....and cruise control. AC was an option we didn't get    Seeing as how we have a half square mile of acreage, it gets used 8 hrs a day, 5 days a week, just to keep up. Not to mention our 10 other 6' mowers. My old 8N, with a Woods 6' belly mower, has never been rebuilt, so I'm afraid to use a non-detergent. It'd probably knock the sludge off the internals and plug everything up in short order. It's been my only mower for the last 16+ years, with no end in sight. Not bad for a $2500 purchase.

      I'm down to my last eight cardboard cans but have three cases of GT1 "green" in the plastic bottles. I have no problem using it despite being 40 years old. I appreciate everyone  else's opinions and concerns/cautions. Kendall saved me when "free" Valvoline failed me way back last century. I do use other "modern" oils where the situation warrants them like roller cam stock engines in my Ranger and wife's Explorer. VR1 20-50 in the enclosed race car hauler's 521.

Haha, my low end Gravely Z34.  Yes, some of those get way up there.

Hmmm, his might be a toro?  It is red and recall it might be turbo charged?  His is open seat(no cab).

My 149 cost me $600.  The 127 was $300.  I rebuilt the motor in the 127 for near nothing.  The shop did all the work, including balancing the crank for free because I'm a nice guy LOL!!  The same shop does my motor work, so you can understand the connection and why I get good service.

Back to the original topic...

Old oil has old inferior additives. Oil companies have spent billions of dollars developing better additives, take advantage of it. I would use a modern name brand synthetic and not look back.

   Oil usage is by FAR the most debated subject on any forum I have ever seen. Everyone seems to have "their" favorite and engine failure is not rampant. So "to each his own".

This.

Changing oil on a regular reasonable mileage interval is way more important than anything else. Especially if you are running modern oil. There are always exceptions, and certain types of oil can help if you have special circumstances, but most stock to street-strip level stuff you can run just about anything in and change it and it'll be fine.

A close 2nd is what car wax to use....at least on Chevy Forums since they don't know their ass from a hole in the ground when it comes to things mechanical! LOL
