    alright i want to hear when you should be able to switch to synthetic oil. and exactly why you should wait. not just the standard because you have to wait for break in. i have done alot of research on oils and have found that most of the new dino oils today have way less zinc causing premature cam and internal part failures. as a matter of fact castrol is now making an oil with a higher concentrate of zinc. to combat this problem.

    I know the dealer i bought mine from puts syn in them. I changed my oil at 1,000 miles and have been using mobil 1 since. I have always used this in my cars, my 1986 iroc camaro which is known for smoking on initial start up has yet to puff 1 cloud at 140,000 miles(engine 305 untuched) just a tune up at 60,000 and 120,000. I live by mobil 1 full syn.
    Ps: i change my oild every 2500 or 3 months. I never miss. Even if im out of town ill do it in a parking lot.

    I have always heard that you can change to synthetic at any time, but once you change you cannot go back. I was told that you cannot mix synthetic and non synthetic oil. I dont know why, but I listened.

    I'm not sure about not being able to switch back..whether it's dino to synthetic or the other way-around. Synthetic oil has different molecular properties that should not be mixed with dino oil. If one did want to switch back, I would use a flushing agent prior to making the switch. Amsoil sells a flushing agent and recommends this when switching from dino to their synthetic products.

    I put Amsoil in my motorcycle.. and I have noticed a 5-10 degree lower operating temperature in my bike since I made the switch..

    You can change back without a problem.
    You can mix dino and synthetic if it's the same brand and weight.
    That what a blend is but only 10-15% synthetic.
    I prefer 100% synthetic..

    From Amsoil's site and I would think Mobil would be the same.

    Are AMSOIL Synthetic Motor Oils and petroleum motor oils compatible?

    AMSOIL synthetic motor oils are fully compatible with all petroleum motor oils, and there is no danger in mixing the two. Mixing AMSOIL and petroleum oil, however, is not a recommended as a general practice. Performance and long drain intervals will be sacrificed and the oil should be promptly changed, at maximum, within the next 3,000 miles.

    I bought my '06 4x4 access cab new, ran the factory oil 1000 miles, ran new filter and Castrol multi-vis 5000 miles, then switched to Amsoil filters and Amsoil 100% synth from then on. I have 50,000 miles on this motor now. One quart down every 4 or 5000 miles would be excellent oil mileage. My V6 does not use oil. Period. I never have to top the oil off between changes, which is every12 months regardless of miles put on.

    hey i finally changed from conventional to royal purple full synthetic 5w 30 i bought a new toyota oil filter and after firing up the motor and letting the oil run itself through the motor what a difference, the temp gauge is alittle lower (nothing extreme) and the motor is 100% more quiet than running conventional oil. my wife of all people who knows nothing about engines even noticed. although im running the airconditioning on max air the compressor is still robbing the motor of power, but thats expected. it was a toss up between r/p or red line i got the r/p extremely cheap. does anyone know where i can get redline at a decent price. and again i cant believe the cams and valves have silenced from the old toyota valve ticking and clicking. i cant wait to get red line oil, if i can get it as cheap as i got royal purple. one more question. when i release the brakes from a red light or from a dead stop the rearend makes a nice jolt almost every time. i have taken it in and they told me its the driveshaft contracting, it getting very annoying and louder , is it something else, i had the brakes inspected all okay from the dealer, its concerning me cause it feels like a slight slip, please help its becoming more constant , thanks again and be safe

    If you have a warranty on your truck for 100k miles and don't plan on keeping it much past that point - is there a reason to spend the extra money and run synthetic or can I just keep running the cheap stuff. I have 15k on my truck as of now and get my oil changed every 5k miles.

    Overreacting probably lol. I ran synthetic in my 07 Impala SS. But I've been running whatever the dealer uses now at 5k miles.

    There is no need to wait at all to put synthetic in your engine. It will break in just fine.

    As said above, synthetic and non can be mixed or switched between without issue.

    Guess I should add to my post that when I ran synthetic in my previous vehicle I started at the first oil change, no issues. So I'd agree, no need to really wait if you're planning on using it.

    Many vehicles are filled on the assembly line with full synthetic. It does not affect the break in period.

    Thanks for your help Chaddawkins. Guess you never learned that if you don't have anything nice to say, don't say anything at all. I ran synthetic in my Tundra because it had the trd supercharger and the dealer recommended it. My new tacoma has the automatic V6 (nothing fancy).
