Fully synthetic: Castrol Formula RS 10W/50 or Caltex Havoline Fully Synthetic 5W/40?

**wiretap_md** · July 17th, 2004 04:05 PM

Which is better? Found these 2 products kasi at Ace Hardware and Robinson's Handyman. Both almost have the same price and have the API-SL rating. Thanks!

I think based on our weather condition and worst driving condition, 10W50 will perform better than a 5W40. I'm using Castrol Magnatec right now and I feel it to be better than other semi-synthetic oil brands.

Castrol's formula RS has a good following in europe but so does caltex/texaco in the US.

Have you heard of Liqui-moly full synth 5w40? It's known as Lubri-moly in the US but is a german made oil- great reputation from the users. Competitively priced, about P2k for 5L locally.

Castrol RS 10W50 is a GREAT oil!!!! This is what they use in BMWs in germany and netherlands.

This is what I use in my E36 as specified by Mosselman Turbo Systems NV.

isn't the castrol rs that is locally available a 10w40? that's the one i have in the shop eh.

anyway, it's a good oil. i recommend it kapag synthetic yung habol ng owner

Since we're on the topic of motor oils... is the Castrol RS 10w40 better than the Mobil1 5w50 syn? I checked out the Mobil1 website, the 5w50 synthetic is not listed in their product line, does that mean the stocks available here are old stocks?

The Castrol RS I saw available at Ace Hardware was the 10w50 variant.

**woodfire** · July 22nd, 2004 09:13 PM

The Castrol RS I was referring to is 10W50 which is standard oil of bimmers in Germany and Netherlands.

Mosselman Turbo Systems also specify Castrol RS 10W50 in turbo charged bimmers.

Hi Eric,

A gallon (4 liters) of Castrol RS is about Php 2,300.00. Its a fully synthetic oil. The container has the picture of J.P. Montoya as the endorser.

True Value in Shangrila Mall and Rockwell Powerplant has them.

P 2,200 at SM Ace hardwares.

Just seen it lately.

**bm5er** · July 23rd, 2004 09:16 AM

Many thanks, both.
Will check it out.

The castrol formula RS only comes in 10w50 locally. Their magnatec is 10w40 but is a semi-synth oil thus cheaper too.

ILuvDetailing
The mobil 1 site is a US product list only and they don't carry 5w50 there. You can find it in the mobil.com.au site.

ooopsss..... my bad guys... just took a look at the formula rs in the shop and tama nga na 10w50. hehe! sorry bout that!
