Ya know...
After years of carefully reading/discerning/following many recommendations for “lubrication types” from vehicle owning novices to racing pros to factory engineers to OEMs to lubrication manufacturers and from other “experts”... I’m getting ever closer to trying a high grade synthetic oil in one of my classic flat tappet high performance car/truck engines, or in one of my standard power range flat tappet twin screw marine V8s, or in one of my roller bearing lifter newer model auto/SUV that have relatively high mileage. Because all my engines have only been high grade dino oiled for years I simply wonder if upon repeat usage of syn oil it may begin to open up currently closed (by years of accumulated gunk) deficits in seals and might even ruin the seal materials in the 1967, 1977, and 1985 (Buick Wildcat, Tolly Twins, Chevy 4WD – respectively).
Probably for closest check regarding difference of syn compared to dino oil would be to continue dino oil in one and begin syn oil in the other of the Tolly’s twins. That said... I’m a stickler in keeping engine compartment clean and bilge oil free. Sure would be bummer to have one of the twin 350/255 hp engines begin to leak oil out its seals. Also, although both engines are running equally strong – port had complete rebuild and starboard had just complete top end rebuild some few hundred hours ago... so... would the dino – vs – syn test twixt the twins be slanted in any way??? I guess I’d try the syn oil in the port engine that had complete rebuild.
I don’t alter my ongoing successful MO's easily and adhere to the money saving fact: “If it ain’t broke don’t fix it!”
I also adhere to the quote I copied below from my post # 46... So, if I do try syn oil in one or another of my engines I will follow the intent stated therein. And, when/if I do try synthetic oil I’ll post my conclusions on TF; after a fair amount of time and a number of oil changes.
Post # 46: “Foundation of keeping enclosed mechanical operations in best condition, i.e gears, bearings... or other items requiring lubrication-barriers: Keep the appropriately correct lubricants clean and in good condition with consistent fluid changes at proper intervals; replaced or cleaned filters if so equipped."
