What is a good Synthetic blend?

[Bulli]

Well i have an uncle that doesn't know [censored] about cars except how to pump gas into it.
I do all the maintainance to it and he never has time to stop by or drop of the car so i can work on it.
Around October i changed his oil and from running regular 5-30 gtx i put in valvoline durablend 5-30 especially since winter rolled around and he never warms up his car and drives like 5 miles to work.

car never sees warm temps.
When he got the car he came every 3k miles to get the oil changed and now since he is getting LAZY he is coming in when the oil has around 5 k miles on it.

i want to give him syn. blend but not tell him like i didnt tell him last time so he can still try to come at around 3-5 k miles.

i dont want to run dino in his car because i dont think it can last that long. with this kind of driving 99% city.

I heard good things about dura blend so thats why i went with it
but what about others oil like M1 7500?
Also i was thinking about Maxline syn blend but is that applicable since the car has around 30k miles

Planty of others good ones out there, but you should be able to find either one of these easily. They will not cost you an arm or a leg either.

valvoline maxlife

 

[deven]

what kinda car? How many miles?

 

[Bulli]

120k miles honda accord with a noisy engine. most likely a rod knock

 

[dorkiedoode]

i use maxlife for my accord.

I'll play the devil's advocate...

I tried Castrol's Syntec blend and my 2005 4.3 V6 loved it. When I changed it out it looked really good - the engine was quiet the whole time I used it - 5w30 during the winter here in Houston. Dern good semi-synth IMHO. Cheers!

On order of price:
Motorcraft
MaxLife/DuraBlend
Hold on...

It's kind of silly to get into brands, doing regular maintenance is the most important thing.

Any oil is fine at the 3k-5k mark.

I use Motorcraft. No one is making me do it.

whatever syn blend is the cheapest is the best for you!

Bulli: Rod knock?! If so, it will be dead soon (within days or weeks, even at 10 miles a day) and any oil you used wouldn't matter. More likely it's not a rod knock, or you'd already be putting an engine in it, or he'd be looking at new cars.

Any of the high mileage blends should do just fine on this engine but you might consider a 5W20 (gasp!). On a short hop car, the lighter oil will circulate faster from a cold start and it's those cold starts and short hops that are killing this car.

agreed on the 5-20 if it is newer Accord. FWIW I make my own synthetic blend: 2 qts Castrol Syntec and 21/2 qts Castrol GTX 5-20-has been working fine

pennzoil or QS truck/suv blend, valvoline durablend, syntec blend, mobil clean 7500... its all the same. use what ever is cheapest. i like maxlife, personally.

oh, and chekc out QS winter synthetic blend in the blue bottles. its specially formulated for winter and you can get it DIRT cheap at the end of the cold season, to stock for next winter
