Well, my truck is getting up there in miles, aprox. 80,000. I am thinking that I may want to switch to a synthetic or synthetic blend. Are these types of oil better for higher mileage engines, or should I just switch to the high mileage oil. I don't have a preference of brands. I have always used quaker state, so I will probably stay with that. Just trying to get some info.
Thanks,
Randy
I think that with a chevy 80K is just getting it broken in. However, on the subject of oil Mobile One and Royal Purple are the ones I use. I do not have any statistical data and I am not an expert but these are the two that I use.
I have heard that if you change to synthetic you are not supposed to go back to standard oil. dont know if that is true or not. I only run synthetic and change the oil at 7K miles. :twocents:
yuck, parafin based crude oil!!! Does Qstate and Pennz still wax coat the insides of the engine? I quit using both of them after seeing what those oils do to insides of an engine block. Build-up so heavy that some of the return holes in the heads and valve lifter valley area filled in and valve springs so coated that you could not even see the springs any more.
I heard it's just best to stay with what you've always ran. I only use mobel1

I just went to M1 in a 175K mi LS400 Lexus... seems to run fine still. I have M1 in my Z and WRX too.
I change the filters every 5K and dump it all around 20K...reason being is when you change the filter you have to add a quart also. I've done this for a while and the truck runs great. :smile:
Well since I do this for a living Ill give you my opinion. I used mobil 1 and it was great, then I started using royal purple and it was alot better. I would not use a high mile oil b/c it is just the same as basic oil with some added not worth the money. I also agree with the penz and quacker diss. It doeshave wax in it and wll build up on your motor. I would do a motor flush, and then use mobil or royal purple. With the purple you will gain some lost hp. Might not notice at first but I say its the best. If you live in the houston area I can hook you up with some royal purple for real cheap and I also can d the motor flush for you, just let me know.
ditto...flush you motor and go to a synthetic...motor will thank you for it :jump: i use castrol syn because i can get it at any walmart..they carry mobil 1 also.
djkir23, give us houston guys an address where you work. If you have a business I will start using you for oil changes. :lol:
PM me if you want
Is there a way to do the engine flush at home? I hate to go to a place that will charge me out the ass for something I can do at home. Unfortunately I don't live in the houston area, I live in the Dallas area. Thanks for the input, but I have a hard time beleiving it is only Quacker state that has a problem with paraffin in their oil, as most companies probably get their oil from the same place. If all the paraffin business is true, I will probably switch to a synthetic oil after I get an egine flush.
Thanks,
Randy
