What's the consensus on this? Benefits, pitfalls etc..?
No pitfalls...if you can afford the extra money, Use Mobil1 Synth. More importantly, your filter. At ALL costs, stay away from Fram products.
but - a synth w/ a good filter will go 6000 miles that's half as many oil changes
Laughing....I might be one of those people who for the most part remembers to change my oil every 3000 miles but occasionally forgets and does go over 5000
Im not worried about the cost difference, I just want to protect my engine. I had heard that once you start using synthetic it's best to stay with it, is that true?
So synthetic but no Fram filters?
Good reading...here's the bottom line:
Thank you guys....Im going to take the advice to heart!
Synthetic it is
Consumer's Report magazine did a study on the relative merits of regular versus synthetic oil some years ago (6 to eight years). They tested several engines to 100,00 miles and came to the conclusion that under most normal applications such as in an automobile, synthetic oil is a complete waste of money. They found that synthetic oil did not perform demonstrably better if a routine maintenance schedule was observed. That means changing the oil and filter at the manufacturer's prescribed intervals.
Synthetic oil does have an advantage when used in a high temperature environment such as in air-cooled engines. Synthetics retained their viscosity longer than normal oil and tended to be less prone to burning or breakdown when subjected to high temperatures. I use synthetic oil in the generator on the motor home because that engine is air-cooled. Also on the lawn mower, chain saw, weed trimmer - anything that runs at very high temperatures. I've used regular oil in every motor vehicle engine I've ever owned and had no lubrication related problems - ever.
Basically, if you put synthetic oil into a water-cooled automobile engine you're spending three to five times more than you should and the increase in protection is insignificant.
...except for the fact sythetics today go for 6-10K miles between changes...and protect better than dino, there's little difference
Perhaps, but driving beyond the recommended oil change interval may void your warranty (if that is an issue). Also, running that long without changing the oil tends to cause an accumulation of particulate matter. That is ultimately what causes the most damaging wear to an engine. No oil, regardless of how slick it may be, can perform its function once it has become contaminated.
