I'm not mechanically enclined so, I really don't know what that means.

I have a 2003 Taco 4 wheel drive with about 90,000 miles. No rough off driving. Thinking of changing to Mobile 1 synthetic. I think I remember that after several thousand miles, that the tolerances created over the miles, will let the much thinner synthetic oil leak through all the gaskets, etc. that the regular oil does not seep through. Usually short under 10 mile runs. Maintained regularly, and at the crazy 3000 miles, and I am getting to old to do it at the 3K. miles. Knot that is probably not necessary! Do I have too many miles to switch to the Mobile 1 synthetic? Thanks, Randy.
Switch to AMSOIL Signature Series and change only every 25,000 miles ,change filters every 12,500 miles! Synthetic does not seep,thats a myth! save money in the long run !
The old issue was..... dino oils detergents would cause seals to swell, then when synthetic was used, it would seep past the gaps because it didnt cause the seals to swell.
I wouldnt go past 5k miles on synthetic WITHOUT an oil analysis from blackstone labs. Otherwise ur just assuming ur oil is good. Also dont forget, just because annoil may be synthetic doesnt mean an oil filter has less work to do and will last extended periods.
Again, i suggest an oil analysis instead of blindly taking suggestions of 10, 15, 20k+ change intervals... its highly dependent on evironment, current engine condition, driving habits, and who knows what else..... lets leave that to those scientists.
Email Blackstone Labs for answers with questions then and send a sample !
Also send a sample to AMSOIL ?
No thanks, i drop my oil erry 5k and refill with mobil1 and oem filter.
I had a 2007 2.7L Tacoma, and it was 5.7 qt with filter. I used Amsoil Signature Series 0W20 with amsoil filter and went 12-15k miles between changes solely depending on color and feel of the oil.... No problems. I traded in 2016 at 138k miles to a 2012 4.0L Tacoma which has a smaller sump (only holds 5.2qts with filter). I now use Amsoil Signature Series 0W30 and only log 5-8k miles between changes again based solely on color and feel. The bigger engine and smaller sump make the difference ... Ive used Amsoil and their filters since 1975 and kinda know what works. However am still leary of going the 25k miles between changes ... Just sayin
Upon purchase of my 2012 4.0L Tacoma prerunner .. it was averaging 17 mpg ... After switching to Amsoil Signature Series 0W30, Amsoil oil filter, and using only one oz of their Amsoil Performance Improver (API) per tank of gas for six tanks ... I am now getting 20.5 mpg ... Quite a nice improvement! ... I plan on changing the trans fluid and diff to amsoil also...
So ur telling me if i use amsoil 0w30, i can get 3.5mpg more?
So around 23 or 24 highway?
I experienced a mpg increase upon switching to amsoil 0w30, using their PI (performance improver) for several tanks, and a K&N air filter... yes
I use Amsoil and experienced an increase in cost. However I am willing to pay since I'm hard on my truck and I have a supercharger.
Sweet, 23/24 mpg sounds good.
Ppl already get pissy with my 20mpg.
Wait, 5 to 8k oil?
So, are you still saving money?
Hmm, im curious since almost all manufacturers want to push their mpg by using splitters, air dam, spoilers, certain tires, and such costly measures dont factory fill with amsoil.
Should either save them a ton of money in r&d, or at the least provide even better numbers than just the wind tunnels can achieve.
Saving on gas mileage and engine life ...
