Amsoil or Royal Purple Engine oil?

[Axela72]

Hi,

 

Saw from some articles that Amsoil is Group IV while, Royal Purple is Group IV with some Group V additives oil.

 

However, heard that Royal Purple thin before 10k km mileage (8k km?). Not sure how true it is. But below links show us that RP seem one of the best:

If intend to use for 10k mileage, which is the better choice with better performance and FC?

 

Currently, understand that they are both at the same price. For 42k km mileage car, should we choose a W30 or W40 type?

 

Kindly advise..Thx

 

BTW, has been using Schaeffer all the time. Since it is no longer as cheap in the past, must as well change to one of the the above more premium brand instead.

use both before, think amsoil is better. unless RP is cheaper, otherwise, Amsoil wil be a better buy.

Clear winner... Amsoil

 

No TC, W30 will do. Amsoil SSO is the best engine oil available for N/A.

Amsoil for 10k OCI. RP only suitable for 5k OCI.

 

And again...no FI then go for w30.

Very obvious engine roughness after 6-7K on RP. Engine remains smooth on Amsoil thru 10K mileage.

Bro, go for Amsoil ...

 

Heard many whom say RP breaks down at around 6-7K range

 

If you don't mind going for oil change at every 5K interval then it's alright

Go for Amsoil AMO 10w40, the high ZINC formula would definably help on protection during high load and boost.

I change out the RP after 2 tank of petrol.....

I have been using RP 0w30 oil since 2005 and have never regretted it, and my ride is a Frosty TC.

Between these 2 Amsoil, currently using 100% 5W30, may consider to change to Redline for this next servicing.

amsoil of course!

Bro, can try MX trading for amsoil. I'm using amsoil 5w30 and engine still quite smooth after 5k usage...

Amsoil 5-30W so far so good, second time using it 20,000km & 30,000km

Am also on Amsoil 5w30, engine revs and is very responsive.

However find that the engine is a tad loud.. so may try 5w40 next time to go for more protection.
